Let a voltage source (v(t)=4 cos left(omega t+60^{circ}ight)) be connected to an impedance (Z=2 / 30^{circ} Omega).

Question:

Let a voltage source $v(t)=4 \cos \left(\omega t+60^{\circ}ight)$ be connected to an impedance $Z=2 / 30^{\circ} \Omega$.

(a) Given the operating frequency to be $60 \mathrm{~Hz}$, determine the expressions for the current and instantaneous power delivered by the source as functions of time.

(b) Plot these functions along with $v(t)$ on a single graph for comparison.

(c) Find the frequency and average value of the instantaneous power.
