A series circuit has an inductor L, a capacitor C, and a power source of variable angular frequency ω. At the angular frequency, ω0, the inductive reactance equals the capacitive reactance. Calculate i) the angular frequency ω0, and ii) the reactances of the inductor (XL) and capacitor (XC) for L= 220.0 mH and C= 8.25 μF.
An alternating current power supply of rms voltage 120.0 V and frequency 80.0 Hz is connected to a parallel plate capacitor. The rms current in the circuit is 200.0 mA. Calculate the capacitance of the parallel plate capacitor.
