The given circuit diagram shows a series LCR circuit linked to a variable frequency 230 V source:
(a) Verify the source frequency which drives the circuit in resonance.
(b) Get the impedance of the circuit and the amplitude of current at the resonating frequency.
(c) Verify the rms potential drops across the three elements of the circuit.
(d) How do you describe the observation that the algebraic sum of the voltages across the three elements obtained in (c) is greater than the supplied voltage?
