Question

In the part of a circuit shown in figure, the potential difference $\left(V_G-V_H\right)$ between points $G$ and $H$ will be:-

• A. 0V
• B. 15V
• C. 7V
• D. 3V

Answer 1

Answer: (C)

Using KCL current through $1\Omega$ is $2A$ upwards.
Now $V_G-2\times 4+3-2\times 2+2\times 1=V_H$
$\Rightarrow V_G-V_H=7V$
