Which one of these is NOT a basic solid-state component?

The correct choice identifies a circuit breaker as not being a basic solid-state component. Solid-state components are electronic devices that are made from solid materials, specifically semiconductors, and they function without moving parts. Diodes, transistors, and integrated circuits all fall into this category as they rely on the behavior of semiconductor materials to control and manipulate electrical signals.

A diode allows current to flow in one direction, while a transistor acts as a switch or amplifier for signals, and an integrated circuit combines multiple electronic components into a single chip to perform complex functions. In contrast, a circuit breaker is a mechanical device designed to interrupt the flow of electrical current to prevent overload or short-circuit conditions. It typically uses moving parts (like levers or magnetic mechanisms) to open or close the circuit, which does not fit the definition of a solid-state component. Thus, the circuit breaker stands out as the correct answer for being not a basic solid-state component.
