The very word current means 'flow'. Electric current is the flow of electric charges. There are two kind of electric charges. Scientists considered the electric current as the flow of positive charges. But in case of solid metals, only negatively charged electrons are able to move freely where as the positively charged protons are held firmly within the core of the atoms. So electric current is due to negatively charged electrons. Now we have to differentiate these two. How? Let us consider the current due to flow of positive charges as conventional current flow. Hence conventional current direction is always opposite to the direction of flow of electrons. To keep the charges in motion we need a force to push them. So we use a chemical cell which has electrical potential difference between the two terminals. This potential difference is named as " electro motive force", in short "emf". So emf is responsible to make electric charges to flow.

Controls the flow of electric current?
a generator
How does the increase or decrease of potential difference affect the flow of the electric current?
Increase or decrease in potential results in the change in direction of the flow of electric current.
