what is difference between current and voltage

Expert Answer
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.
