A certain circuit has a 25-Ω resistor and one other component in series with a 12-V (rms) sinusoidal ac source. The rms current in the circuit is 0.317 A when the frequency is 150 Hz and increases by 25.0% when the frequency increases to 250 Hz.
(a) What is the second component in the circuit?
(b) What is the current at 250 Hz?
(c) What is the numerical value of the second component?
