You are provided with a resistor, a key, an ammeter, a voltmeter, four cells of $1.5$ 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.
