Question

In the circuit shown, the point $B$ is earthed. The potential at the point $A$ is

• A. 14 V
• B. 24 V
• C. 26 V
• D. 50 V

Answer 1

Answer: (B)

Current in the given circuit $i=\frac{50}{(5+7+10+3)}=2A$
Potential difference between $A$ and $B,V_A-V_B=2\times 12$
$\Rightarrow V_A-0=24V\Rightarrow V_A=24V$
