JEE Main 2022 · 26 Jul · Shift 2, Physics question 44

A battery of 6 V is connected to the circuit as shown below. The current I drawn from the battery is :

Wheatstone-type network: two 3 Ω resistors along the top, two 6 Ω along the bottom, a 5 Ω bridge between their midpoints; the 6 V battery in series with 2 Ω across the outer ends, current I.
Choose one option
Answer and worked solution

Official answer: A

Balanced bridge. 33=66\frac33=\frac66, so the 5 Ω carries no current.

Resistance. 6∥12=46\parallel12=4 Ω, plus 2 Ω: 6 Ω, so I=1I=1 A.

(A)
