QUESTION:

(a) Employ superposition to determine the individual contribution from each independent source to the voltage v as labeled in the circuit shown in Fig. 5.57. (b) Compute the power absorbed by the \(2\ \Omega\) resistor.

ANSWER:


(a) Applying the superposition theorem, the voltages due to the three sources can be calculated as:

\begin{align*} v_{1} &= 6 \ \mathrm{V} \cdot \left ( \frac{2 + 3}{2 + 3 + 5} \right ) = 4 \ \mathrm{V} \\ v_{2} &= 10 \ \mathrm{V}
