JEE Main 5 April 2026, Shift 1, Physics Q38

Question 38 of 75 in this shift, Physics question 13 of 25, Section A.

Refer to the figure given below, current between terminals AA and BB is ________ A.

The figure, in words

Between terminals A (left) and B (right) are four parallel rows. Rows 1-3 each contain three 5 V cells (+ terminal on the left) alternating with three 3 ohm resistors in series (cell, resistor, cell, resistor, cell, resistor). Row 4 has three 3 ohm resistors in series with no cells.

Question text from the official JEE Main paper published by NTA; answer from the final answer key. Chapter, topic and idea tags, difficulty and skill are Lumi’s. This question needs a figure we do not reproduce; it is described in words above. Lumi analyses 108 of the 174 JEE Main shifts held from 2017 to 2026.
