Answer 2

Answer:

The potential drop between A and B is equal to 8V.

Explanation:

The equivalent emf is equal to zero because the polarity of the batteries is opposite to each other.

Then, the current in the circuit is zero.

Now,

Apply Kirchhoff's voltage law,

The potential drop between A and B = 2×0+8+4×0

                                                  = 8V

So, the potential drop between A and B is equal to 8V.
