Kirchhoff's Laws & Measuring Instruments question from JEE Main 2025 (22 Jan, Shift 2)

Answer: 1

1. In steady state the $1\ \mu$F capacitor blocks current, so everything to its right carries no current.
2. At B: $3\ \Omega \parallel 6\ \Omega = 2\ \Omega$ to the bottom line; with $2\ \Omega$ in series: $4\ \Omega$.
3. This is in parallel with the $4\ \Omega$ diagonal: $R_{eq} = 2\ \Omega$.
4. $I = \frac{2}{2} = 1$ A
5. So the answer is 1 A.
