Energy per coulomb

Energy per coulomb

Simple circuit with a cell supplying e.m.f. and a lamp transferring energy with p.d., with arrows showing charge flow around a complete circuit

In a complete circuit, charge carries energy around the loop. The charge is not used up; instead, a source gives energy to the charge and components take energy from it.
