diagram for demo

P-N Junction as a rectifier: Diode bridge rectifies AC voltage. The diode will allow current to flow in one direction, and virtually no current to flow in the opposite direction, depending on the polarity of the voltage. In this demo, a 6.3 V.A.C. (sine wave) is injected into the circuit. The waveform at 'A' will be either a negative or positive 1/2 wave, depending on how the reversible diode is plugged in. The waveform at 'B', shown on the scope, will be a full-wave rectified signal (fluctuating D.C.)
