Kirchhoff's Laws & Measuring Instruments question from JEE Main 2026 (5 Apr, Shift 1)

Q9JEE Main 2026 · 5 APR · SHIFT 1Medium

Kirchhoff's Laws & Measuring Instruments

Refer to the figure given below, current between terminals $A$ and $B$ is

______ A.

Show answer and solution

Answer: (b)

Each of the top three rows: emf $3 \times 5 = 15$ V, resistance $3 \times 3 = 9\ \Omega$ .
Three identical rows in parallel act as one cell: $E = 15$ V, $r = \frac{9}{3} = 3\ \Omega$ .
The bottom row ( $9\ \Omega$ ) is the load: $I = \frac{15}{3 + 9} = 1.25$ A
So the answer is (b) 1.25 A.
