Difference Between Ac And Dc Current Pdf. The direction of current flow will change at normal time interval then this kind of current is known AC or alternating current whereas the DC is unidirectional because it flows in a single direction only. Can be transmitted over long distances easily 4.
An AC generator equipped with a device called acommutator. Electric charge in alternating current AC on the other hand changes direction periodically. In alternating current the current reverses direction 50-60 times in a second depending on the frequency.
Nov 18 2014 Direct current is not easily converted to higher or lower voltages.
The major drawback of using DC is it starts deteriorating with distance. Can produce direct current Use of a device called arectifier. The maximum voltage at which Electrical Power is. DC is constant with time while AC changes at every instant of time.
