A

6\,\text{V}

battery is to be connected across a

12\,\Omega

resistor. The laboratory has two voltmeters available: Range A:

0

–

5\,\text{V}

and Range B:

0

–

15\,\text{V}

. Which voltmeter range should be selected to measure the potential difference across the resistor? Show your working.
