JEE Main 26 July 2022, Shift 2, Physics Q44

Question 44 of 90 in this shift, Physics question 14 of 30, Section A.

A battery of 6V6V is connected to the circuit as shown below. The current II drawn from the battery is :

The figure, in words

Resistor network drawn in a rectangle: top row has two 3 ohm resistors; a 5 ohm resistor is drawn vertically in the middle between the top row and the bottom row; the bottom row has two 6 ohm resistors; along the bottom wire a 6 V battery and a 2 ohm resistor are drawn, with current I marked by an arrow at the left of the battery. A wire runs down the right side of the network to the 2 ohm resistor.
