Chapter-7|Alternating Current |NCERT 12th Physics: Mean or Average Value of AC: It is defined as the value of AC, which would send same amount of charge through a circuit in half cycle that is send by steady current(DC) in the same time (i.e T/2) through the same circuit. Note: We cannot calculate average value of […]
Chapter-7|Alternating Current | NCERT 12th Physics: Alternating Current: If the direction of current changes alternatively and its magnitude changes continuously with respect to time is called alternating current. Alternating current changes continuously between zero and maximum value and flows in one direction in the first half cycle and in the opposite direction in the next
