JEE Main 31 January 2024, Shift 2, Physics Q56

Question 56 of 90 in this shift, Physics question 26 of 30, Section B.

In the following circuit, the battery has an emf of 2V and an internal resistance of 23Ω\frac{2}{3}\Omega. The power consumption in the entire circuit is __________ W.

The figure, in words

Square network: 2 ohm resistors on the top and bottom sides, left and right sides plain wires; two diagonals, each made of two 2 ohm resistors, crossing at the centre. A 2 V battery in series with its internal resistance 2/3 ohm is connected between the left and right sides of the square.
