An ac generator has a frequency of 1300 Hz and a constant rms voltage. When a 463-Ω resistor is connected between the terminals of the generator, an average power of 0.260 W is consumed by the resistor. Then, a 0.0830-H inductor is connected in series with the resistor, and the combination is connected between the generator terminals. What is the average power consumed in the inductor–resistor series circuit?
