Question

In the given circuit, the emf 'E' of the cell is ______.

विकल्प

• 0 V

• 2 V

• 3 V

• 1 V

Answer 1

In the given circuit, the emf 'E' of the cell is 3V.

Explanation:

Applying Kirchhoff's voltage law in loop ABCDA,

- 2 - 0.1(1) - 0.1 (3) - 0.1 (5) - 0.1 (1) +E= O

∴- 2 - 1 +E = O

∴ E=3 V
