Why is junction diode used for rectification?

Explain the use of junction diode as a full wave rectifier by drawing circuit diagram and draw the form of input and output waves.

Zener diode is used as

A sinusoidal voltage of amplitude 25 volts and frequency 50 Hz is applied to a half wave rectifier using PN diode. No filter is used and the load resistor is 1000 Omega . The forward resistance R_(f) ideal diode is 10 Omega . Calculate. (i) Peak, average and rms values of load current (ii) d.c power output (ii) a.c power input (iv) % Rectifier efficiency (v) Ripple factor.

When p-n junction diode is forward biased ………

Assertion : p-n junction diode can be used even at ultra high frequencies. Reason : Capacitative reactance of a p-n junction diode increases as frequency increases.
