Question

1.      The peak voltage of a.c. supply is 14.14 A at 50 Hz. Find the rms value. How much time will the current take in reaching from zero to max value?​

Answer 1

Explanation:

Now, the peak value of the current can be obtained from the r.m.s. value of the current as: I0=√2Irms=√2×10=14.14 A.

Answer 2

The time will the current take in reaching from zero to max value is 0.005.
