They are exactly analogous to water pressure and water flow through a hose. That's why flowing electrons is called a current, just like a water current. Voltage is the electromotive force (the force to move electricity) that wants to push electrons through a wire the way that water pressure (which we could call the hydromotive force by analogy) is the force that wants to push water molecules through a hose. The wire and the hose each offer resistance to the force. Less resistance or more pressure (force) means more flow, whether that be gallons/minute of water or amperes of current.

Current is Flow of Electrons though a system.

 

Voltage is the Force (EMF) which drives Electrons to Flow.

 

Voltage in Open Circuit is also called EMF

EMF in Closed Circuit is also called Voltage.........

Current is simply the flow of electrons

 

Voltage is the amount of energy needed to lift a charge from the point or High potential to Low potential .
