Vedclass · Answer

(D) Direct Current $(DC)$ is a type of electric current that flows in only one direction.Unlike Alternating Current $(AC)$,which periodically reverses its direction and magnitude,$DC$ maintains a constant polarity and magnitude over time.Frequency is defined as the number of cycles per second of an alternating waveform.Since $DC$ voltage does not oscillate or change its direction,it does not complete any cycles.Therefore,the frequency of $DC$ voltage is $0 \ Hz$.

What is the frequency of $220 \ V$ $DC$ voltage? (In $Hz$)
