What is the main difference between voltage, EMF and a potential difference?
Let's see the following experiment. A container 'A' is kept at a height. Another container 'B' is kept at lower height. A is connected to B using a tube with valve 'C'. A is filled with water.
When C is opened water from A flows to B.
Here the force of gravity makes the water flow. This is EMF. The force responsible for flow.
Gravity acts differently as per height difference. This is nothing but potential difference. It is the same as voltage.
The amount of water flowing is nothing but current.
The valve C is nothing but a switch.
The length, bends and restrictions in flow of water in the pipe is nothing but resistance
