Question 159: Current Electricity

Question

A 16 $$\Omega$$ wire is bend to form a square loop. A 9V supply having internal resistance of 1$$\Omega$$ is connected across one of its sides. The potential drop across the diagonals of the square loop is _______________ $$	imes$$ 10
$$-$$1
V

Accepted Answer

Here assume current as
By KVL in outer loop
9 $$-$$ 12i $$-$$ 4i = 0
16i = 9
8i = $${9 \over 2}$$ = 4.5
= 45 $$	imes$$ 10
-1
