Electricity is a flow of electric charges in a conducting medium.
When a potential difference is created across the two terminals of a conductor, then an electrostatic force (field) acts on the charges (free conducting electrons) present in the material. The electrons gain energy and move (jump from one atom to another) along the conductor towards the positive terminal.
Thus charges flow in a conductor as long as a potential difference exists.
The potential difference across the ends and the resistance of the material regulate the current in an electric circuit.

The flow of charges (+ve or -ve) constitutes the electricity.
When there's the potential difference(difference in electric pressure at both the terminals) then the electrons move towards the positive terminal, which creates a flow of electricity through the circuit.
The factors to control or regulate the current through an electric circuit are:
- Resistance
- Voltage
I hope it will help u !!!
