Question: 1 / 400

In conventional current flow, the direction of current is considered to move from which terminal to which terminal?

Negative to positive

Positive to negative

In conventional current flow, the direction of current is considered to move from the positive terminal to the negative terminal. This convention dates back to the time before the discovery of electrons, when it was assumed that current was the flow of positive charge. As a result, when analyzing circuits or understanding electrical principles, it is important to remember that conventional current is defined to flow from higher potential (positive terminal) to lower potential (negative terminal).

This understanding is crucial for effectively analyzing circuit diagrams and equations, as many are based on this convention. The concept of current flowing from positive to negative is standard in both theoretical calculations and practical applications in electrical engineering and physics.
