1. An RLC oscillator circuit contains a 53.0 Ω resistor and a 1.60-mH inductor. What capacitance is necessary for the time constant of the circuit (the 1/e value) to be equal to the oscillation period?
2. At what frequency will a 15.0-?F capacitor have reactance XC = 230 ??
3. A label on a hair dryer reads "110 V, 1150 W". What is the peak current in the hair dryer, assuming that it behaves like a resistor.
