These cookies do not store any personal information. We use a voltmeter to measure potential difference (or voltage). That is because, it is the causative agent of electricity or currents that drive every electrical device. Any charge that comes in vicinity of another charge experiences a force of repulsion or attraction. A term must now be introduced which is: Electrical resistance or just resistance. It could also be defined as the change in the potential energy that occurs due to transport of a unit charge from one point to the other. The current through a component depends on both the resistance of the component and the potential difference across. This is a fully differentiated lesson, including PPT, differentiated worksheet and corresponding past paper questions. of energy to each coulomb of charge
