I have the following question that I require some help:

a) The resonant frequency of the circuit.

b) The magnitude of the circuit current at resonance.

c) The magnitude of the voltage across the inductor at resonance.

d) Account for the magnitude of the voltage across the inductor, given that the supply voltage is only 10V?

e) Sketch a phasor diagram showing the relative phases and magnitudes of the current and all the voltages in the above circuit.

f) A fault has occurred in the above circuit and the inductor needs to be replaced. However, the only inductor available has a value of 18 mH. The variable capacitance is adjusted to bring the circuit back to its original resonant frequency. What value of capacitance does the circuit now possess?

Circuit has the following components and values in series.

V = 10volts

R = 10 ohms

L = 10mH

C = 25.33nF

Answer for a = 10kHz

Answer for b = 1A

Answer for c = I x XL = 628.319V

I am unsure on d, e and f.

Any help is appreciated
