When an AC source is connected across a 1500 resistor the rm

When an AC source is connected across a 15.0-0 resistor, the rms current in the resistor is 7.28 A. Find the rms voltage across the resistor. Find the peak voltage of the source. Find the maximum current in the resistor. Find the average power delivered to the resistor.

Solution

I = 7.28 A , and R = 15 Ohms

a.
Voltage = V = I R = 109.2 V

b.

Peak Votlage = V = 109.2 x 2^0.5 = 154.43 V

c.
Max current = I_max= 7.28 x 2^0.5 = 10.295 A

d.
Power = I^2 R = 794.976 W
