JEE Main 25 July 2022, Shift 2, Physics Q42

Question 42 of 90 in this shift, Physics question 12 of 30, Section A.

A current of 15 mA flows in the circuit as shown in figure. The value of potential difference between the points A and B will be :

The figure, in words

Circuit: a rectangular loop with a 10 kΩ resistor on the top branch and a 5 kΩ resistor on a middle horizontal branch, both connecting the left vertical wire to a right vertical wire; a 10 kΩ resistor in the right vertical wire below the middle branch, ending at terminal B; the left wire runs down to the bottom where a 5 kΩ resistor is followed by terminal A, with an arrow marked 15 mA pointing toward A.
