decelerates and stops moving Figure 3-1 illustrates these concepts.

Figure: 3-1 Conceptual illustration of charge movement for conduction currents.

a) Charge velocity versus time after E field applied.

b) Energy is extractedfrom the applied electric field versus time.

Figure: 3-2 When an electric field is applied, unbound electrical charges accelerate to a terminal velocity. After initial acceleration, velocity becomes constant and a continual transfer of energy to

the surrounding material in the form of heat occurs

All the time that charge is moving, the moving charge is working against

its
