In this tutorial, we are going to show you how to make a continuity tester (DC) at home. A continuity tester is electric equipment that helps in determining the electric path between the two points.
So let us first gather all the essentials that will be required to do this science project.
- 9-volt battery
- LED bulb
- Copper wire
- Aluminum wire (10 cm)
- Plastic box
- Empty refilled the pen
Steps To Make Continuity Tester (DC)
Step 1: First take a plastic box and make holes in it using soldering iron (as shown in the picture).
Step 2: Now attach the switch bulb and buzzer in their respective holes.
Step 3: Now connect battery connector with buzzer and further connect buzzer with LED bulb with copper wire.
Step 4: Now connect copper wire and aluminum wire using soldering iron and pass it inside the prefilled pen and build two testers.
Step 5: Now connect the battery wire with the one tester and another tester with the switch.
Step 6: Now connect the battery connector to the battery. To test the continuity tester, use the switch or touch both the tester and you will see that the led bulb will glow.
Now the continuity test is ready to represent its activity.
Things To Remember
- Work carefully during using a soldering iron.
- Working slowly and carefully during cutover.
- It is advisable to work on a self-healing mat or a piece of scrap cardboard to protect your work surface.
- Learn all you can about the materials and techniques you’re using.
- Work carefully during wire attachment.
- The battery will be warm during the experiment, be careful with it.
