) A 200mA, 50Hz AC current source (of negligible output impedance) is connected across the same RL series combination of Q3(a). (i) Calculate the resistor voltage, inductor voltage and source voltage, all as phasors (you may ignore the transient effects which occur just after the AC source has been connected). Sketch the voltage phasors of Q3(b)(i) on a fully-labelled phasor diagram, together with the source current 200mA/0° as a phase reference (graph paper is not required). (iii) Calculate the maximum rms power that can be provided by this AC source and, by first calculating the circuit's power factor, calculate the rms power dissipated in the resistor.
