Contactless Voltage Tester – Circuit and Making

Sep 9, 2020Sartaj Singh Virdi8 CommentsElectronic Projects for Kids

CONCEPT OF THE CIRCUIT In this Contactless Voltage Tester circuit the current induced in the Antenna Coil when bringing it to close to the AC Voltage (Wire or Switch) is subsequently amplified by three transistors connected in the series to light an LED or you may add a buzzer in parallel to the LED. The circuit
