inductor L and assume they have been connected for Consider a circuit consisting of a sinusoidal source V s (t) = cos (t) u (t) volts connected in series to a resistor R and an a very long time.
Let R = 1Ohm and L = 0 H. Compute the instantaneous and the average powers delivered to the resistor.
Hint: In the above parts problem use phasors or the trigonometric formula
cos(a) cos(ß)=0.5[cos(a- ß)+cos(a+ ß)]
