Which option is NOT one of the three basic circuit parts?

Explanation:
A simple circuit is understood as three essential pieces: a source of electrical energy, a load that uses that energy, and a switch or control element that completes or interrupts the path. The transformer is a specialized device that changes voltage and current in AC circuits through electromagnetic coupling; it’s not part of the basic trio needed to form a simple circuit. It’s used for voltage transformation and impedance matching in more complex circuits, rather than being one of the fundamental three parts. So the option that does not belong with the basic parts is the transformer.
