MCQ
In the circuit shown, the point ‘$B$’ is earthed. The potential at the point ‘$A$’ is ............. $V$
  • A
    $14$
  • $24$
  • C
    $26$
  • D
    $50$

Answer

Correct option: B.
$24$
b
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 $ ${V_A} = 24\,V$
