What is the direction of flow of electric current taken as by convention?

Electric current is conventionally considered to flow from the positive terminal to the negative terminal of a power source. This convention dates back to the early days of electrical science when the direction of flow was thought to be the movement of positive charges. Even though we now know that electric current is actually carried by electrons moving in the opposite direction (from negative to positive), the original convention remains in use. Would you like to delve into the historical reasons behind this convention?

By convention, the direction of electric current is considered to flow from the positive terminal to the negative terminal of a power source. This is opposite to the actual flow of electrons, which move from the negative terminal to the positive terminal. This convention dates back to Benjamin Franklin's time, before the discovery of the electron.
