Revise Edexcel GCSE Physics 10.1.4 Potential difference and voltmeters with the question bank and revision guides.
Recall that a voltmeter is connected in parallel with a component to measure the potential difference (voltage), in volt, across it. • Explain that potential difference (voltage) is the energy transferred per unit charge passed and hence that the volt is a joule per coulomb.
