CAIE IGCSE Physics 4.2.3.2 E M F Is Measured in Volts V Questions

Learn that e.m.f. is measured in volts, equivalent to joules per coulomb, and read it in circuit measurements while distinguishing it from current and resistance units.

Exam points

State that e.m.f. is measured in volts (V), equivalent to joules per coulomb, recognise e.m.f. readings and units in a battery or circuit measurement, and distinguish e.m.f. units from current units in circuit data.

[Maximum number: 1]

The unit of the two electrical quantities electromotive force (e.m.f.) and potential difference (p.d.) is the volt (V).

State one other similarity between e.m.f. and p.d.
