A coil of resistance 2 Ω and inductance 5 mH is connected in series with a 2μF capacitor across a 6 V variable frequency supply.
(i) Considering how XL, XC and R vary with frequency, generate a formula for resonance frequency.
(ii) At the resonant frequency determine:
a) Circuit impedance
b) Circuit current
c) The volt drop due to resistance (R), inductance(L) and capacitance(C)
d) Power factor and phase angle
e) Power dissipated by the circuit
