What type of current flows from the positive terminal to the negative terminal?

Conventional current refers to the flow of electric charge, which is defined as moving from the positive terminal to the negative terminal of a power source. This concept has historical significance, as the direction of current flow was established before the discovery of the electron, which actually moves in the opposite direction. Conventional current is widely used in circuit analysis, allowing engineers and scientists to communicate and calculate the behavior of electric circuits effectively.

In the context of the other types of current mentioned, AC (alternating current) continuously changes direction and does not have a consistent flow from positive to negative. DC (direct current) does flow in one direction, from positive to negative, but typically the term "conventional current" is used to specifically describe the flow direction as originally defined. Impulse current refers to very short bursts of high current, often associated with transient events, and does not maintain a steady flow from one terminal to another.

Thus, the reference to conventional current is accurate because it aligns with the established understanding of current flow direction in electric circuits.
