6.

The impedance at the resonant frequency of a series

*RLC*circuit with*L*= 20 mH,*C*= 0.02 F, and*R*= 90 is_{W}7.

A 6.8 k resistor, a 7 mH coil, and a 0.02 F capacitor are in parallel across a 17 kHz ac source. The coil's internal resistance,

*R*, is 30 . The equivalent parallel resistance,_{W}*R*(eq), is_{p}8.

Referring to Problem 20, what is the total parallel resistance (

*R*)?_{p(tot)}9.

A 200 resistor, a coil with 30 of reactance, and a capacitor of unknown reactance are in series across an ac source. The circuit is at resonance. Circuit impedance
