CSEC Physics · 1996 · Paper 2 · Question 4(a)(iii)

The circuit shown in Figure 6 investigates the relationship between applied potential difference and current for a 10 Ω carbon resistor using a 3.0 V battery of negligible internal resistance, an ammeter of negligible resistance, and a 20 Ω rheostat.

Complete Table 2 to show how the meter readings change when the sliding contact on the rheostat is moved from end X to the other end Y.

This question uses a figure or table from the paper — you'll see it when you practise.
