9702Practical circuits

A cell with internal resistance is connected to a variable resistor R as shown. The resistance of R is gradually decreased. How do the current I and the terminal potential difference (p.d.) across the cell change?

  1. Acurrent I decreases, terminal p.d. across cell decreases
  2. Bcurrent I decreases, terminal p.d. across cell increases
  3. Ccurrent I increases, terminal p.d. across cell decreases
  4. Dcurrent I increases, terminal p.d. across cell increases

As printed in the paper
