A cell is linked to a fixed resistor. As time passes over a long interval, the internal resistance of the cell rises. How does this increase in internal resistance affect the electromotive force (e.m.f.) of the cell and the power dissipated in the fixed resistor?
- Ae.m.f. decreases, power dissipated decreases
- Be.m.f. decreases, power dissipated no change
- Ce.m.f. no change, power dissipated decreases
- De.m.f. no change, power dissipated no change
