1- A series L-R-C circuit consists of a 262 Ω resistor, a 23.9 mH inductor, a 10.28 µF capacitor, and an AC source of amplitude 26 V and variable frequency. If the voltage source is set to 4.7 times the resonance frequency, the impedance of this circuit is:
Express the answer as a whole number.?
2-An AC source whose rms voltage is 72 V is in series with a 167 Ω resistor and a capacitor whose reactance Xc is 117 Ω at the frequency of the source. In the figure, the rms voltage (as a whole number) across the capacitor is:?
