A voltmeter has a resistance of 6.0 kΩ6.0\text{ k}\Omega6.0 kΩ and reads 1.5 V for every scale division on the meter.
A power supply of emf 12 V and negligible internal resistance is connected across this voltmeter and a resistor in series. The voltmeter reads two divisions.
What is the value of the resistor?
1.8 kΩ1.8\text{ k}\Omega1.8 kΩ
2.4 kΩ2.4\text{ k}\Omega2.4 kΩ
18 kΩ18\text{ k}\Omega18 kΩ
24 kΩ24\text{ k}\Omega24 kΩ
