As shown in the illustrated devices and symbols, which of the symbols shown in the illustration represents a standard normally closed relay contact? Illustration EL-0005
AI Explanation
The correct answer is B.
The symbol F shown in the illustration represents a standard normally closed relay contact. This is based on the standard electrical schematic symbols used in the illustration, where F denotes a normally closed contact that is open when the relay is de-energized.
The other answer choices do not represent a normally closed relay contact. Option A (E) likely represents an electrical power source, Option C (I) represents a normally open relay contact, and Option D (K) likely represents some other electrical component.
