For resistor failure, possible causes may be__________ .
A)wrong heater; relay in high ambient
B)abrasive dust; very heavy duty; no lubrication
C)overcurrent; moisture; corrosive atmospheres
D)abrasive dust; dirty oil; water in tank

Question

Quizplus · Accepted Answer

Overcurrent can cause the resistor to burn out, moisture can corrode the resistor, and corrosive atmospheres can also damage the resistor. The other options may cause problems in other parts of the system, but they are not directly related to resistor failure. Overcurrent, moisture, and corrosive atmospheres are all potential causes of resistor failure. Wrong heater and relay in high ambient (choice A) may cause other issues but are not directly related to resistor failure. Abrasive dust and heavy duty without lubrication (choice B) may cause wear and tear on equipment but are not specific to resistor failure. Abrasive dust, dirty oil, and water in tank (choice D) may cause contamination and malfunction, but again, this is not specific to resistor failure.
