a circuit is driven by an 100 rms volt ac source at a frequency of 200 hz. what is the average power dissipated if a) there is negligible inductance and 10 ohms of resistance, b) there is negligible resistance and .2 h inductance, and c) there is 10 ohms of resistance and .2 h of inductance? in all cases there is no capacitor and no capacitive reactance.
