Problem

A conductor gives a current of

0.5\,\text{A}

when a potential difference of

3\,\text{V}

is applied across it. Assuming the conductor obeys Ohm’s law, what current will flow when the potential difference is

7.5\,\text{V}

? a)

1.0\ \text{A}

1.5\ \text{A}

1.25\ \text{A}

0.83\ \text{A}
