what do you remeber on curent
> define : Electric is the rate of flow of electric charges
> Short From : I
> SI unit : A (ampere)
> instrument : Ammeter

In an electric circuit , the energy for the electric charges to move around a circuit is given by a electrical energy source such as the battery of the cell.

whe there is a potential difference across a conductor.

SI unit: volt (V)
