why A.C current attract and D.C current repel
Asked by Anjishnu Bhattacharjee | 26th Jun, 2011, 12:00: AM
Alternating current (AC) varies between positive peak value to negative peak value in a fixed time interval. For time when it is in positive region, it attracts and when it is in negative region it repels.
While in DC there is no variation in its magnitude and polaity. Therefore it only attracts and DC of high magnitude can be vergy dangerous.
