Question

1. the conventional current flow theory states that current flows in a circuit from the negative side of the voltage source to the positive side of the supply.

true

false

Explanation:

Define conventional current flow theory

The concept of Electric Current can be described using two different theories of flow. Conventional current flow theory, originally proposed by Benjamin Franklin, assumes that current consists of positive charges moving through a circuit. Therefore, under this theory, current is defined as flowing from the positive terminal of the voltage source, through the external circuit, and returning to the negative terminal of the supply.

Define electron flow theory

In contrast, electron flow theory describes the actual physical movement of charge carriers in metallic conductors. Since electrons carry a negative charge, they are repelled by the negative terminal of a voltage source and attracted to the positive terminal. Thus, electron flow theory states that current flows from the negative side of the voltage source to the positive side.

Evaluate the statement

The statement in the question asserts: "The conventional current flow theory states that current flows in a circuit from the negative side of the voltage source to the positive side of the supply."

Based on our definitions:

• Conventional current flows from positive \((+)\) to negative \((-)\).
• Electron flow flows from negative \((-)\) to positive \((+)\).

Since the statement attributes negative-to-positive flow to conventional current theory, the statement is false.

Answer:

• True
• False (Correct answer)
