Conventional Current

We know that the current flowing in a circuit is due to the negative electrons flowing from the negative terminal of a battery to the positive terminal.

Negative to Positive is the flow of electrons

Before the discovery of the electron scientist thought that the current flowed from the positive terminal to the negative one. By the time the electron was discovered many laws had been established to explain the world around them using current as flowing from positive to negative.

Positive to Negative is the Conventional Current
