Q1:

In the given circuit, viewed from AB, the circuit can be reduced to an equivalent circuit as

A 5 volts source in series with 10 Ω resistor

B 7 volts source in series with 2.4 Ω resistor

C 15 volts source in series with 2.4 Ω resistor

D 1 volt source in series with 10 Ω resistor

ANS:B - 7 volts source in series with 2.4 Ω resistor

For RTh, Voltage source will be short circuited RTh = 2.4 Ω, VAB = 10 - 6 I 7 V.
