An electric circuit is a closed loop through which electrons flow. [1] X Research Source A simple electrical circuit consists of a power source (battery), conductor and resistor (light bulb). [2] X Research Source In the circuit, electrons flow from the battery through the wire to the light bulb. Get enough electrons, the light is on. When installed correctly, with just a few simple steps, you can light up your bulb.
Steps
Create a simple circuit with batteries
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/c7/Make-a-Simple-Electrical-Circuit-Step-1-Version-3.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-1-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/c7/Make-a-Simple-Electrical- Circuit-Step-1-Version-3.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-1-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Gather all the supplies. To create an electrical circuit, you need a power source, two insulated conductors, a bulb, and a lamp base. The power source can be any type of removable battery or block battery. The rest of the supplies can be found at the hardware store.
- When choosing a light bulb, do not forget about the power of the battery.
- To simplify wiring, use pre-wired battery caps, 9V batteries, or block batteries.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d9/Make-a-Simple-Electrical-Circuit-Step-2-Version-3.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-2-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d9/Make-a-Simple-Electrical- Circuit-Step-2-Version-3.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-2-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Peel off the power cord. For the circuit to work, the wires need to be completely exposed. Therefore, you have to separate the sheath at the end of the wire. Use pliers to peel off the insulation, about 2.5 cm at each end.
- If you don’t have a stripper, you can use scissors to carefully cut off the insulation of the wire.
- Be careful not to cut the wire.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e5/Make-a-Simple-Electrical-Circuit-Step-3-Version-3.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-3-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e5/Make-a-Simple-Electrical- Circuit-Step-3-Version-3.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-3-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Insert the battery into the base. Depending on the type of battery used, you may not need this step. If using multiple removable batteries, you will need a battery holder. Install batteries next to each other, paying attention to the correct negative and positive directions.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d0/Make-a-Simple-Electrical-Circuit-Step-4-Version-3.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-4-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d0/Make-a-Simple-Electrical- Circuit-Step-4-Version-3.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-4-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Connect the cord to the power supply. The wire will conduct current from the battery to the bulb. The easiest way to wire up is to use electrical tape. Connect one end of the wire to the other end of the battery, making sure to make contact between the wire and the metal end of the battery. Do the same with the other wire and the other end of the battery.
- Alternatively, if using a battery cap, attach the lead to the top of a 9V or block battery.
- Use caution when creating electrical circuits. Although rare, there is still the possibility of a very slight shock when touching the wire directly while connected to the battery. You can avoid this by touching only the insulated part of the wire or removing the battery until it is time to install the light.

Secure the other end of the wire to the metal screw on the base of the lamp. Take the peeled section at the end of each wire and bend it into a U shape . [3] X Source of Study Loosen the screw on the lamp base just enough to thread this U around the screw. Each wire is connected with a screw. Tighten the screw and make sure the metal core of the wire is in contact with the screw.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/6/67/Make-a-Simple-Electrical-Circuit-Step-6-Version-2.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-6-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/6/67/Make-a-Simple-Electrical- Circuit-Step-6-Version-2.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-6-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Check the electrical circuit. Fasten the bulb to the base. If the circuit is connected correctly, the light will be on when fully installed.
- Bulbs can heat up quickly. Therefore, be careful when disassembling and assembling.
- If the bulb does not light up, check to make sure that the wire is in contact with the battery terminal and is connected to the metal part of the screw.
Install the switch
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/81/Make-a-Simple-Electrical-Circuit-Step-7-Version-2.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-7-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/81/Make-a-Simple-Electrical- Circuit-Step-7-Version-2.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-7-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Collect supplies. To install the switch, instead of two, you now need three pieces of wire. Once you have removed the housings and connected them to the battery box, you can proceed to install the switch.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e1/Make-a-Simple-Electrical-Circuit-Step-8-Version-2.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-8-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e1/Make-a-Simple-Electrical- Circuit-Step-8-Version-2.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-8-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Install the switch. Take the peeled end of a cord that is connected to the battery and bend it into a U. [4] X Source of Study Loosen the screw on the switch and thread this U-wire underneath. Tighten the screw to ensure the connection to the metal core of the wire is maintained.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/3d/Make-a-Simple-Electrical-Circuit-Step-9-Version-2.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-9-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/3d/Make-a-Simple-Electrical- Circuit-Step-9-Version-2.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-9-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Connect the third wire to the switch. Bend one end of the wire into a U shape. Thread it under the other screw to connect to the switch. Tighten the screw to ensure that the metal part of the screw is in contact with the metal part of the wire.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/2c/Make-a-Simple-Electrical-Circuit-Step-10-Version-2.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-10-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/2c/Make-a-Simple-Electrical- Circuit-Step-10-Version-2.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-10-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Light bulb connection. Take the end of each wire (one from the source and one from the switch) and bend it into a U shape. Loosen the screw at the base of the light just enough to thread the U of the wire around the screw. Each wire will be connected with a screw. Tighten the screw, making sure that the wire is kept in contact with the metal screw.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d5/Make-a-Simple-Electrical-Circuit-Step-11-Version-2.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-11-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d5/Make-a-Simple-Electrical- Circuit-Step-11-Version-2.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-11-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Check the electrical circuit. Fasten the bulb to the lamp base. Switched on! If the circuit is connected correctly, the bulb will light up when fully screwed into the base.
- Bulbs can heat up very quickly. So, be careful when disassembling and assembling.
- If the bulb doesn’t light, check to make sure the wire is in contact with the battery terminals and connected to the metal part of the screw.
Find and handle electrical circuit faults
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e3/Make-a-Simple-Electrical-Circuit-Step-12-Version-2.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-12-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e3/Make-a-Simple-Electrical- Circuit-Step-12-Version-2.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-12-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Make sure all power cords are properly connected. To create a circuit, every wire must be in contact with the metal part of each part. If the bulb doesn’t light, check each battery terminal and the screw in the base to make sure the wire is connected to the metal. [5] X Research Sources
- Make sure screws are tightened to maintain connection.
- In some cases, you may need to remove additional insulation from the wire.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/39/Make-a-Simple-Electrical-Circuit-Step-13-Version-2.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-13-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/39/Make-a-Simple-Electrical- Circuit-Step-13-Version-2.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-13-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Check the bulb filament. The light will not light if the filament is broken. Shine the bulb under the light and make sure that the filament is a mounting part. Try a new bulb. If shadows are not the problem, continue with the next fault finding and troubleshooting step.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/2/29/Make-a-Simple-Electrical-Circuit-Step-14-Version-2.jpg/v4-728px-Make- a-Simple-Electrical-Circuit-Step-14-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/2/29/Make-a-Simple-Electrical- Circuit-Step-14-Version-2.jpg/v4-728px-Make-a-Simple-Electrical-Circuit-Step-14-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,” bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div>”}
Check the battery power level. If the battery is dead or low on power, the light may not have enough power to light up. Use an electrical tester to check the power level or you can simply replace the battery with a new one. If this is the case, the light bulb should theoretically come on as soon as the battery is changed. [6] X Research Sources
