Question 348Electricity & Electronics - Assistant Engineer

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.
