What is the potential difference between the terminals B and D in the given figure?
(Consider battery to be ideal with emf `epsilon = 6V`)

Options

A. Zero
B. 1.5 V
C. 2 V
D. 3 V

Answer

A

Explanation

The given figure is a circuit of balanced Wheatstone bridge.

Point B and D would be at the same potential, i.e., `V_B – V_D = 0` volt
