Electrochemical Units and EMF

An explanation of voltage (electromotive force), amperage, current (coulombs), energy (joules) and Faraday's constant. A contextual example is provided for understanding.

Electricity is charges in a sense. The charges could be static (static electricity) or they could be in motion as in here. Current is used to represent like the speed of motion but instead of considering the distance electrons travel in a second (speed), current is the amount of electricity (or charges) that passes any point in the circuit in a second. So the amount of electrons that the anode losses in a second is the current which is the same everywhere. Just like water current in a pipe is constant because the amount of water fetched in a second is the same amount that enters the pipe in a second and the same amount that crosses any cross-section in a second. It's like the rate at which the charge moves but with respect to the amount of charge. But in the real sense, electricity is movement of charges because we say there is electricity in a place when charges are in motion.
