AC DC Polarity Tester Circuit Using LEDs - Electronics

This electronics video tutorial explains how to design an AC DC polarity tester circuit using LEDs or light emitting diodes. Both LEDs will be ON when an AC (Alternating Current) power source is connected to the circuit. Only one LED will be ON when a DC (Direct Current) power source is connected to the circuit.
