Given information

There is a loop where we need to apply Kirchhoff's rule and examine whether the sign of the battery's emf depends or not when current passes through the battery. And also need to explain the change in terminal voltage with the change of direction in current flow.

Step-by-step explanation

Step 1.

Kirchhoff’s law states that the sum of voltage differences around a closed loop in a circuit must be zero. 

A loop in a circuit is defined as the path which ends at the same point where it starts.
