Express your answer in
rectangular and polar forms, and draw the impedance diagram
For the circuit in Fig.
Determine I, VR, and VC in phasor form.

Calculate the average power delivered to the circuit.
Draw the impedance diagram.
Draw the phasor diagram of the voltages E, VR, and VC, and the current I.
Find the voltages VR and VC using the voltage divider rule, and compare them with the
results of part (a).
Draw the equivalent series circuit of the above as far as the total impedance and the
current i are concerned.
