Question

the potential difference between point a and b is ​

Answer 1

Answer:

REF.Image.

Let the potential at

lower potential terminal

of the battery be 0.

Then,

V at A = (2)-V

V at B = (0) + V

Where V = (5)i,

i=

5Ω+5Ω+5Ω

2V

=(

Answer 2

Explanation:

A uniform magnetic field of induction B acts normal to the plane containing the rails and the wire inwards. Is a current source providing a constant current in the circuit. Then the potential difference between A and B is.
