Electrical components can be categorized into two groups:

Electrical components can be categorized into two groups:

• A. Controls and loads
• B. Motors and switches
• C. Sensors and gauges
• D. Valves and fans

Answer: (A)

In electrical systems, components are commonly grouped by function: those that regulate or control power, and those that actually use power. Controls are devices that govern when and how current flows. They include switches, relays, controllers, timers, and sensors that trigger actions. They don’t consume much energy themselves but determine the operation of the circuit. Loads are the devices that draw power to do work or produce something useful. They include motors, compressors, fans, heaters, and lights. So, in a refrigeration scenario, the control elements decide when the compressor should run, while the compressor and fans are loads that convert electrical energy into mechanical work and motion. The other options mix device types rather than describe the functional split between controlling the circuit and consuming power.
