The charge e on one electron is negative and equal in magnitude

to 1.602 10-19 C which is called as electronic charge. The

charges that occur in nature are integral multiples of the

electronic charge.

Voltage is the energy required to move a unit charge through an element,

measured in volts (V).

•The charge flowing through a wire and voltage across the wire are shown in Fig. 1 (a).

Sketch the corresponding current with time, the power absorbed by the wire with time, and

find the energy absorbed by the device from 0 to 10s.
