(c) At resonance, what is the phase angle of the source current with respect to the source voltage? How does this compare to the phase angle for an L-R-C series circuit at resonance?
(d) Draw the circuit diagram for an L-R-C parallel circuit. Arrange the circuit elements in your diagram so that the resistor is closest to the ac source. Justify the following statement: When the angular frequency of the source is w = w0, there is no current flowing between (i) the part of the circuit that includes the source and the resistor and (ii) the part that includes the inductor and capacitor, so you could cut the wires connecting these two parts of the circuit without affecting the currents.
(e) Is the statement in part (d) still valid if we consider that any real inductor or capacitor also has some resistance of its own? Explain.
