Answer Posted / sree ranga prasad

AC(ALTERNATIVE CURRENT)
-IN AC MAGNITUDE IS VARYING
-AC HAVING FINUTE TIME PERIOD
-AC TERMINALS REPRSENTED BY PHASE AND NEWTRAL
-IN AC SINGLE PHASE AND THREE PHASE AVALIBLE
-IT HAS SOME FREQENCY

DC(DIRECT CURRENT)
-IN DC MAGNITUDE IS CONSTANT
-HERE TIME PERIOD IS INFINITY
-HERE FREQENCY IS ZERO
-TERMINALS ARE REPRSENTED BY +,-
