i/p: 12v 1Hz.
Bridge rectifier diodes replaced with Led's.
Load is applied to 470ohms resistor.
This circuit shows the Conduction of two leds during +ve half cycle while the remaining two doesnt conduct electricity. During -ve half cycles corresponding leds glow while the other two leds doesnt conduct. Thus the AC is converted into DC at the load ie.. Load Led.
