b. Draw the admittance diagram.

c. Find the voltage E and the currents I_R and I_L in phasor form.

d. Draw the phasor diagram of the currents I_s. I_R. and I_L, and the voltage E.

e. Verify Kirchhoff’s current law at one node.

f. Find the average power delivered to the circuit.

g. Find the power factor of the circuit, and indicate whether it is leading or lagging.

h. Find the sinusoidal expressions for the currents and voltage if the frequency is 60 Hz.

i. Plot the waveforms for the currents and voltage on the same set of axes.
