Which electrical schematic symbol represents a normally open thermostat? Illustration EL-0059
AI Explanation
The correct answer is D.
The electrical schematic symbol that represents a normally open thermostat is the symbol labeled 9 in the illustration EL-0059. This is the correct answer because a normally open thermostat is an electrical component that completes a circuit when the temperature reaches a certain threshold, and the symbol labeled 9 is the standard representation for this type of thermostat in electrical schematics.
The other answer choices (2, 7, and 8) represent different electrical components, such as a resistor, a capacitor, and a normally closed switch, respectively, which are not the correct symbol for a normally open thermostat.
