Vedclass · Answer

(B) When an alternating voltage is applied to a $p-n$ junction diode in series with a load,the diode acts as a rectifier.During the positive half-cycle of the input $a.c.$ signal,the diode is forward-biased and conducts current,allowing voltage to appear across the load.During the negative half-cycle,the diode is reverse-biased and does not conduct,resulting in zero voltage across the load.Consequently,the output voltage across the load is unidirectional but varies with time,which is known as a pulsating $d.c.$ voltage.

List $I$	List $II$
$(a)$ Rectifier	$(i)$ Used either for stepping up or stepping down the $a.c.$ voltage
$(b)$ Stabilizer	$(ii)$ Used to convert $a.c.$ voltage into $d.c.$ voltage
$(c)$ Transformer	$(iii)$ Used to remove any ripple in the rectified output voltage
$(d)$ Filter	$(iv)$ Used for constant output voltage even when the input voltage or load current change
