A 16 Ω wire is bent to form a square loop. A 9 V supply having an internal resistance of 1 Ω is connected across one of its sides. The potential drop across the diagonals of the square loop is __________×10-1 V.

Solution

Here assume current as

By KVL in the outer loop

9-12i-4i=0

16i=9

8i=92=4.5

=45×10-1
