Question 152Electricity & Electronics - 1st Asst/Chief

The correct answer is B) its reliability factor will decrease. When a carbon resistor is not properly cooled in electrical equipment, it will generate heat due to the electrical current passing through it. This heat buildup can cause the resistor to change its resistance value over time, which can negatively impact the reliability and performance of the electrical circuit. As the resistor heats up, its internal structure and composition can be altered, leading to a decrease in its reliability factor. The other options are incorrect because A) the resistor value will not change inversely proportional to the heat, C) the reliability factor will not increase, and D) the resistor value will not remain the same under these conditions.
