JEE Main 2025 — 28 January, Evening Shift — Question 67

The value of current $I$ in the electrical circuit as given below, when potential at A is equal to the potential at B , will be $\qquad$ A.

Answer: 2

Numerical answer — enter this value.

$\mathrm{V}_{\mathrm{A}}=\mathrm{V}_{\mathrm{B}} \Rightarrow$ the bridge is balanced

$\Rightarrow \frac{10}{\mathrm{R}}=\frac{20}{40}$

$R=20 \Omega$

$\mathrm{I}=\frac{40}{20}=2 \mathrm{~A}$ A
