JEE Main 29 July 2022, Shift 1, Physics Q55

Question 55 of 90 in this shift, Physics question 25 of 30, Section B.

The current I flowing through the given circuit will be __________ A.

The figure, in words

Circuit with a 6 V battery and three 9 Ω\Omega resistors in a row along the top; a wire connects from the left end of the first resistor over the top to the junction between the second and third resistors, and another wire connects from the junction between the first and second resistors underneath to the right end of the third resistor; the battery is on the bottom branch; current I marked upward on the left.
