QUESTION:
For the circuit shown in Figure P 11.7-3, determine the average power absorbed by each resistor, \(R_1\) and \(R_2\). The voltage source is vs ¼ 10 þ 10 cos \((5t + 40^{\circ})\) V, and the current source is \(i_s\) = 4 cos \((5t - 30^{\circ})\) A.
ANSWER:
Step 1 of 5
Notice that voltage source has AC and DC component.Let’s first consider only DC component of voltage source. The equivalent circuit for DC voltage source is shown in figure below (inductance is short-circuited,current source and capacitance are open-circuited).
