  1. Viewed from the terminal AB, following circuit shown in the figure can be reduced to an equivalent circuit of a single voltage source in series with a single resistor with which of the following parameters?

    1. 4 volts source in series with 10 Ω resistor
    2. 1 volt source in series with 2.4 Ω resistor
    3. 15 volts source in series with 2.4 Ω resistor
    4. 1 volt source in series with 10 Ω resistor
Correct Option: B

Applying Thevenin’s theorem
Req = 6 Ω | | 4 Ω = 2.4 Ω

Vab = 10 - 6
15
= 1 V
10
