# In the circuit shown in figure ϵ_{1} = 3V, ϵ_{2} = 2V, ϵ_{3} = 1V and r_{1} = r_{2} = r_{3} = 1Ω. Find the potential difference between the points A and B and the current through each branch.

Answer :

2V,1A,0A,1A

Here, we will apply KVL

KVL in loop 1 gives

—————(1)

KVL in loop 2 gives

—————(2)

Solving (1) and (2) gives

Current through topmost branch is 1A.

Current through middle branch is 0A.

Current through bottommost branch is 1A.

Therefore, potential difference is
