Question

please solve this question I am really struggling very hard with this one please don't copy from any website​

Answer 1

Answer:

Explanation:

Explanation:

We apply the equation,

U = RI

E - U = rI

E = (R + r) I

The emf is E = 2• 1.9 = 3.8V

The cells are in series-parallel and the internal resistances as well.

The total resistance is,

The current is,

So, the potential difference is,

= U = 18• 0.21 = 3.69V.
