**The figure 2.3 shown below is showing a circuit. In this circuit, current**

*I*can be varied by making use of the variable resistor

*R*2. For different setting conditions of

*R*2, the current flowing in the resistor

*R*1, displayed onthe ammeter, and the potential difference "p.d"across

*R*1, displayed on the voltmeter, are noted and a graph is plotted of p.d. against the current. Diagram 2.4(a) shows the results where the straight line graph passing through the origin indicates that current is directly proportional to the p.d. Since the gradient, that is, p.d./current, is constant, resistance

*R*1 is constant. A resistor, therefore, is a good example of a

**linear device**.
