True or False - When free electrons in a conductor flow in one direction, it is called current of simple current.

The statement that when free electrons in a conductor flow in one direction, it is called current of simple current is accurate. This flow of electrons constitutes what is known as direct current (DC) when they move consistently in a single direction. In a DC circuit, the current remains constant over time, and it is the movement of these free electrons that creates an electric current.

Understanding the dynamics of electron flow is fundamental in electrical theory; when these electrons move uniformly in one direction, it distinguishes it as a simple current. This is different from alternating current (AC), where the direction of electron flow periodically reverses.

While the other choices might focus on aspects of electrical circuits or external factors that influence current, they do not negate the definition of simple current as described in the statement.
