The following statements are related to an RLC circuit connected
across an AC power source. Choose the words that make
each statement true. (i) The voltage across the [(a) capacitor;
(b) inductor] leads the current by 90°. (ii) The voltage across
the [(c) capacitor; (d) resistor] is in phase with the current.
(iii) At resonance, the phase angle Φ between the current and
the voltage [(e) is 0; (f) depends on frequency f ]. (iv) The
maximum and rms voltages from the power source are related
by [(g) ΔVmax = √2 ΔVrms ; (h) ΔVmax = ΔVrms/√2].
