S/C diode as Rectifier

S/C diode has a wide range of application ,one of them is rectification.The diode is used in rectifier circuits to rectified a.c input signal .Here diode and load resistor (RL) are connected in series as given below.The rectified signal (i.e d.c output) is obtained across the load resistor.

Circuit details:

Diode conduct current in forward biased or one direction.So at the time of positive half-cycle of a.c input signal ,the S/C diode conducts this signal in the circuits because of forward bias .As a result the positive half-cycle of input signal appears across the load resistor as shown in figure below.But at the time of negative half-cycle of input a.c signal ,diode does not conduct current because of reverse biased.As a result no voltage appears across the load resistor .In this type of circuits the negative half-cycle are suppressed

but output consist of only positive half-cycle of in put a.c signal.In this way ,S/C diode act as rectifier (i.e a.c input signal changes into d.c out put).
