QUESTION:
a) In the circuits in Fig. P3.7(a)–(d), find the equivalent resistance seen by the source.
b) For each circuit find the power delivered by the source.
ANSWER:Step 1 of 9
Part (a)
Consider the circuit (a),
The equivalent resistance of the circuit can be calculated as,
\(\begin{array}{l} R_{e q}=[(15 \| 60)+(30 \| 45)+20] \| 50+25+10 \\ R_{e q}=\left[\frac{15 \times 60}{15+60}+\frac{30 \times 45}{30+45}+20\right] \| 50+35 \\ R_{e q}=[12+18+20] \| 50+35 \\ R_{e q}=50 \| 50+35 \end{array}
