Electric Current, Voltage and Electric Power

The term electric current is the flow of electrons or electric charges. The drift of electrons is proportional to the amount of voltage or potential difference applied. The more is the voltage, the more will be the electron drift. The amount of electric current a circuit possesses is proportional to the density of electrons or electric charge.
