A $12\text{ V}$ battery is connected in series with an ammeter, a $2\Omega$ fixed resistor and a $0$-$10\Omega$ variable resistor. A voltmeter with high resistance is placed across the variable resistor. The variable resistor is adjusted from zero up to its highest resistance. Which graph shows the way the potential difference (p.d.) reading on the voltmeter changes as the current reading on the ammeter changes?
