The r.m.s. value of an ac of 50 Hz is 10 amp. The time taken by the alternating current in reaching from zero to maximum value and the peak value of current will be?
Added by Anuj C.
Step 1
Given frequency, f = 50 Hz Time period, T = 1/f = 1/50 = 0.02 seconds Time taken = T/4 = 0.02/4 = 0.005 seconds Show more…
