Passive components are types of electrical components that do not generate power; rather, they can only store or dissipate energy. This characteristic fundamentally defines components such as resistors, capacitors, and inductors.

The statement that passive components do not supply power to the circuit is accurate because these components can only use the power supplied by active components (such as batteries, generators, or operational amplifiers) or dissipate energy, primarily in the form of heat. They do not contribute additional energy to the circuit, which distinguishes them from active components that can both store and generate energy.

In contrast, other statements imply functions that are outside the nature of passive components. For example, passive components do not amplify signals, as amplification requires active components that can increase the power level of a signal. Additionally, while passive components consume power in terms of energy lost in resistance or energy stored temporarily in electric and magnetic fields, they do not create or introduce additional power into a circuit. Thus, understanding these principles helps clarify the unique role that passive components play in electronic circuits.
