Question

The effective value of current in a 50

cycle a.c. circuit is 5A. What is the value of

current 1/300 second after it was zero?​

Answer 1

Answer:

RMS value of AC current=5A

Peak value = 5√2A

frequency=f=50Hz

Time period=T=1/50 sec

current=I=5√2sun(2π f t) Amp

= √2*sin(100π/300) Amp

=5√1.5 Amp
