I am having trouble working out how to equate capacitance in an RLC series circuit. I have a small paper with both series and parallel RLC circuit question (attached) I believe my equations are correct up until the last capacitance question then I am stuck. I'd greatly appreciate confirmation I am on the right track and guidance in working out capacitance.
Task 1 Parallel RLC Circuit:
A coil of resistance 20Ω and inductance 200mH is connected in Parallel with a 4µF capacitor across a 50V, Variable frequency supply, Calculate
(c )The current at resonance
= 2.5A
(d ) & The Q-Factor of the circuit at resonance
=
Task 2 Series RLC circuit:
The current at resonance in a series LCR circuit is 135µA. If the applied voltage is 3.5Mv at a frequency of 200kHz, and the circuit inductance is 47µF, Calculate:
(a ) The circuit resistance:
= 20.357
(b ) The circuit capacitance:
= = ???
