Question

Electrons in a wire move from point A to point B. What is the direction of the current that flows in the wire?

1) From A to B
2) From B to A
3) There is no current flowing in the wire
4) Cannot be determined

Answer 1

The direction of the electrical current in a wire is opposite to the movement of electrons; hence, if electrons move from A to B, the current flows from B to A, which is known as conventional current.

Step-by-step explanation:

When electrons in a wire move from point A to point B, the direction of the current that flows in the wire is from B to A. This is because electrical current is defined in terms of the direction that a positive charge would flow, and electrons are negatively charged. Therefore, although the electrons move from A to B, the current is considered to move in the opposite direction due to the history of convention set by Benjamin Franklin. This concept is known as conventional current, and it is an important principle in the study of electricity and circuits. Hence, the correct answer to the question is that the current flows from point B to point A.
