Ohm's law

Question

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

Moderate

A

14 V
B

24 V
C

26 V
D

50 V

Solution

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