Question

Viewed from the terminals A and B the circuit given below can be reduced to an equivalent circuit with a single voltage source in series with a resistor with ________

(a) 5 V source in series with 10 Ω resistor

(b) 1 V source in series with 2.4 Ω resistor

(c) 15 V source in series with 2.4 Ω resistor

(d) 1 V source in series with 10 Ω resistor

I had been asked this question in my homework.

My question comes from Advanced Problems on Network Theory in portion Network Theory and Complex Circuit Diagram of Network Theory

Answer 1

Right choice is (b) 1 V source in series with 2.4 Ω resistor

The best I can explain: Applying Thevenin’s Theorem REQ = 6 || 4

= \(\frac{6 × 4}{6 + 4}\)

= \(\frac{24}{10}\) = 2.4 Ω

VAB = 10 – 6 × (\(\frac{15}{10}\)) = 1 V.
