Vedclass · Answer

(C) In a full-wave rectifier, the output is obtained for both the positive and negative half-cycles of the input alternating current $(AC)$.Since the output pulses twice for every single cycle of the input $AC$, the frequency of the ripple in the output is double the input frequency.Given input frequency $f_{in} = 50 \, Hz$.Therefore, the fundamental ripple frequency $f_{out} = 2 	imes f_{in} = 2 	imes 50 \, Hz = 100 \, Hz$.

In a full-wave rectifier circuit, the input frequency is $50 \, Hz$. The fundamental frequency of the ripple is ....... $Hz$.
