Non Contact Voltage Tester
Non-Contact Voltage Tester Overview I will tell you how you can make a simple efficient Non-Contact Voltage Tester by using transistors. You can make this electronic project or circuit by using simple components or elements and test the presence of AC voltages. You don't need to worry about getting zapped because it is a non-contact voltage tester . Components Required for Non-Contact Voltage Tester The following components are required for the generation of Non-Contact Voltage Tester project: Make an antenna with copper wire Light-emitting diode [LED] Transistor BC 547 or any NPN 3.7v Battery Non-Contact Voltage Tester Testing with Diagrams Friends, In this diagram I am showing you that after making the circuit the circuit looks like this. And if you take close near any voltage carrying wire or any other instrument. The LED will blink or turn ON. The blinking and turning ON of LED proves that the nearer wire or any other instrument contains current. Non-Contact Voltage Tester Te...
