Current:- An electric current is the rate of flow of electric charge per unit time.
Potential difference:- Is work done in moving charge from one point to another point .
Resistance:- It is the property of a conductor to resist the flow of charge through it .
Resistivity:- it is defined as the resistance of 1 by a cube of a material of side 1 when current flows perpendicular to its oopposite faces.
Power:- It is the amount of energy transferred or converted per unit time.

Explanation:
- the rate of flow of charges in a conductor is called current .
- Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit.
- Resistance is a measure of the opposition to current flow in an electrical circuit.
- Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction.
- the rate of doing work is called power ..
