The circuit shown contains a cell with negligible internal resistance. The energy transferred per unit charge in driving charge around the complete circuit is $$\(E\)$$. The potential difference (p.d.) across $$\(X\)$$ is $$\(V\)$$. The cell is then replaced with a different cell of the same electromotive force (e.m.f.) that has significant internal resistance. What is the effect on $$\(E\)$$ and $$\(V\)$$ of replacing the cell?
