Electrical Engineering - RLC Circuits and Resonance

To tune a parallel resonant circuit to a higher frequency, the capacitance should be

In a certain series resonant circuit, V_C = 125 V, V_L = 125 V, and V_R = 40 V. The value of the source voltage is

A certain series resonant circuit has a bandwidth of 2 kHz. If the existing coil is replaced with one having a higher value of Q, the bandwidth will

A 9 mH coil is in parallel with a 0.015 F capacitor across an 18 kHz ac source. The coil's internal resistance, R_W, is 60 . The circuit impedance is

A 15 resistor, an inductor with 8 inductive reactance, and a capacitor with 12 capacitive reactance are in parallel across an ac voltage source. The circuit impedance is
