RMS value of AC current = 5 A
Peak value = 5 √2 A
frequency = f = 50 Hz
Time period = T = 1/50 sec
Current = i = 5√2 Sin (2π f t) Amp
= 5√2 * Sin (100π/300) Amp
= 5 √1.5 Amp
Peak value = 5 √2 A
frequency = f = 50 Hz
Time period = T = 1/50 sec
Current = i = 5√2 Sin (2π f t) Amp
= 5√2 * Sin (100π/300) Amp
= 5 √1.5 Amp

given Irms=5.0amp
I0=2–√Ims
f=50cycles/sec,t=1300sec
I=I0sinwt
=2–√×50sin2π×50×1300
=2–√×50×sinπ3
=6.124amp
