Which of the following is NOT a component of normal electrical current?

In the context of electrical circuits, normal electrical current comprises voltage, current, and resistance, which are fundamental electrical properties. Voltage, also known as electrical potential difference, is the force that pushes electric charges through a circuit. Current refers to the flow of electric charge, while resistance measures how much a material opposes the flow of that charge.

Magnetism, while often associated with electrical current through the phenomenon of electromagnetism, is not considered a fundamental component required to define or understand normal electrical current. Instead, magnetism results from the behavior of electrical currents and their interactions with magnetic fields, rather than being a defining aspect of the current itself. Therefore, identifying magnetism as not being a component of normal electrical current is accurate. This clarity helps delineate between the basic electrical properties and the secondary effects of those properties in practice.
