Which component is typically found in the control circuit for providing power to loads?

In a control circuit, the transformer is an essential component that provides the necessary power to operate loads. It typically steps down the voltage from the power supply to a level suitable for the control circuit's requirements. This lower voltage is crucial for the proper operation of control devices, such as relays, contactors, and other automation equipment, ensuring safety and functionality.

Transformers isolate the control circuit from the higher power circuits, which reduces the risk of electrical shock and damage to sensitive components. By supplying a stable voltage to these control devices, they enable reliable operation of the entire system, allowing it to execute commands accurately and efficiently.

In contrast, other components such as fuses, breakers, and receptacles serve different functions. Fuses provide overcurrent protection, breakers offer a means to interrupt the circuit during faults, and receptacles serve as points for plugging in devices, rather than supplying power for control purposes directly. Thus, the transformer's role in providing the right voltage to control circuits is why it is the correct answer.
