In the circuit shown in fig. 5.265, `E_1 = E_2 = E_3 = 2V` and `R_1 = R_2 = 4Omega.` The current flowing between points A and B through battery `E_2` is

Options

A. zero
B. 2 A from A to B
C. 2 A form B to A
D. none of the above

Answer

B

Explanation

For loop (1), `2 + 2 -4I_1 = 0 or I_1 = 1 A`

For loop (2), `-2 -2 +4I_(2) = 0 or I_(2) = 1A`
So the current from A to B is `I_(1) +I_(2) = 2A`.
