Final answer:
Type B power plugs are most likely found in medical facilities in the United States due to their grounding feature and compatibility with 110-120V electrical systems, enhancing safety in such environments.
Step-by-step explanation:
The power plug type Type B would most likely be found in a medical facility in the United States and other areas where this standard is used.
The Type B electrical plug has two flat parallel pins and a grounding pin and is designed for use in 110-120V countries. It is commonly used in hospitals and clinics to ensure grounding and reduce the risk of electric shock, which makes it particularly suitable for environments where safety is paramount, such as medical facilities.
