Answer :
Electric current is the name given to the movement of electrons within a conductor. The change in charge over time ,that is referred to as current.
- Each electron has a unique charge .We often measure in coulombs rather than electrons because there are so many electrons.
- The flow of electrons, or the flow of negative charge, is really in the opposite direction of current, which is a terrible historical decision. In that case, negative current is the correct response.
- The item does not have to be a "conductor" to measure current flow, as a last purely technical point. Since conductance is a continuous scale rather than a binary option, all objects have conductance or, in the other direction, resistance .
