a) A 2.90 H coil with a resistance of 6.41×101 ? is in series with a 1.14×103 ? resistor. This circuit is connected to an AC voltage source that gives 72.0 V (rms) at 65.0 Hz. What is the rms value of the potential difference across the resistor?
b) What is the peak value of the potential difference across the coil?
