Whats the difference and relationships between current and voltage ?

Selected Ans.

Gnerally current is defined as flow,flowing,in movement

Electric Current is flow of electric charge caused by moving electrons.

But there should be some pressure or cause that results in movement of electrons ,and this pressure is called voltage.

Voltage (Voltage, electric potential difference, electric pressure or electric tension ) :

The voltage between two points is equal to the work done per unit of charge against a static electric field to move the charge between two points and is measured in units of volts

is the electric force that causes the free electrons to move from one atom to another.

Current is the effect . Current cannot flow without Voltage.
Voltage is the cause . Voltage can exist without current.

More technically ,

The voltage between two points is equal to the work done per unit of charge against a static electric field to move the charge between two points and is measured in units of volts
