An AC generator supplies 44 rms volts to a 60-Ω resistor at 60 Hz. What is the maximum current in the resistor?
Brilliant_brown [7]

Answer:

1.0639 A

Explanation:

We have given rms voltage V = 44 volt

Resistance = 60 ohm

According to ohm's law V=iR

So 44=i\times 60

i=\frac{44}{60}=0.7333A this is the rms current but we have to find the maximum current

So maximum current i_m=\sqrt{2}i_{rms}=1.414\times 0.7333=1.03693A
