Vedclass · Answer

(C) The frequency of an $AC$ current is defined as the number of complete cycles per second.One complete cycle consists of two alternations (or half-cycles) where the current flows in one direction and then in the opposite direction.Therefore,in one complete cycle,the current changes its direction twice.Given that the frequency is $50\, Hz$,there are $50$ complete cycles in one second.Total number of direction changes $= 50 	imes 2 = 100$ times per second.

How many times does an $AC$ electric current with the frequency $50\, Hz$ change its direction in one second?
