Question

A student wants to use two p-n junction diodes to convert alternating current into direct current$.$ Draw the labelled circuit diagram he/she would use and explain how it work

Answer 1

Working: For the half cycle of input ac, one of two diode gets forward biased and conducts and output current is obtained across RL.For -ve half cycle of input ac, the other diode is forward biased and thus output current is obtained due to this diode in this way we get the output current across load RL for a complete cycle of input ac as shown in fig
