You are provided with a resistor, a key, an ammeter, a voltmeter, four cells of $\displaystyle 1.5$ V each and few connecting wires. Using these circuit components, draw a labelled circuit diagram to show the setup to study the Ohm's law. State the relationship between potential difference (V) across the resistor and the current (I) flowing through it. Also draw V-I graph, taking V on the X-axis.
