What three components are necessary to produce a solid state temperature control?

The correct choice consists of the sensor, control board, and potentiometer, which are integral to producing a solid-state temperature control system.

The sensor plays a critical role by detecting the current environmental temperature and providing that data to the control board. The control board acts as the central processing unit, interpreting the temperature data and making decisions based on pre-set parameters. Lastly, the potentiometer is essential for adjusting the set point or desired temperature; it allows for manual changes to the system’s response according to user requirements.

Together, these components work in synchrony to create a reliable and precise temperature control system that operates without mechanical parts, enhancing efficiency and reducing wear.

Other combinations listed do not offer the same functional capacity needed for a solid-state system; for instance, while a resistor may be useful in certain circuits, it does not offer the controlled adjustability that a potentiometer provides. Similarly, components like relays and circuit breakers are more suited to older mechanical systems rather than a modern solid-state application focused on reliability and precision.
