Which of the following is a characteristic of specialty step-down transformers?

A. Connected in series with the load
B. Used for doorbells and other signaling systems
C. Used for emergency systems in health care facilities
D. Long distance transmission across extended areas



Answer :

Final answer:

Specialty step-down transformers are crucial for emergency systems in health care facilities, providing safe voltage levels for essential equipment.


Explanation:

Specialty step-down transformers are used for emergency systems in health care facilities, providing lower voltage for critical equipment. Unlike transformers connected in series with the load, these transformers serve specific purposes such as reducing voltage for safe residential and commercial use. They are distinct from step-up transformers that increase voltage for long-distance power transmission.
