The rms current in an RL circuit is 0.26 A when it is connected to an ac

Question:

The rms current in an RL circuit is 0.26 A when it is connected to an ac generator with a frequency of 60.0 Hz and an rms voltage of 25 V.

(a) Given that the inductor has an inductance of 145 mH, what is the resistance of the resistor?

(b) Find the rms voltage across the resistor.

(d) Use your results from parts (b) and (c) to show that √V2rms,R + V2rms,L is equal to 25 V.
