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?

2. Bdecreases increases
3. Cno change decreases
4. Dno change increases
