How can we measure the potential difference across the ends of a conductor?
(N/A) The potential difference across the ends of a conductor is measured using a device called a voltmeter.
$A$ voltmeter is always connected in parallel across the points between which the potential difference is to be measured.
It has a high resistance to ensure that it draws a negligible amount of current from the circuit.
