Electric current comes in many forms: current in a wire, flow of ions between the plates of a battery and between plates during electrolysis, as arcs, sparks, and so on. However, here on ...

This has come to be known as conventional current flow. Then in 1897, British physicist Thompson, discovered that current flow was really electrons as he was doing some research on a crt.

Scientists later discovered that current is actually the flow of electrons, from negative to positive. The original definition is now referred to as 'conventional current', to avoid confusion with ...

Electrons flow from the negative terminal through ... It is called the direction of conventional current.

It also includes the symbol for a diode, showing the direction of conventional current flow when the diode is forward biased. (Image: Wikimedia Commons, CC SA 3.0) When a positive voltage is applied ...
