Question 85Electricity/Electronics - QMED70% to pass
Which of the following conditions would most likely lead to the failure of a resistor due to overheating?
AI Explanation
The correct answer is A) Resistor wattage rating one-half that required for the circuit.
This is because if the resistor wattage rating is one-half of what is required for the circuit, the resistor will be subjected to excessive power dissipation, leading to overheating and potential failure. The other options (B, C, and D) would not lead to overheating and failure, as the resistor wattage rating would be sufficient or even higher than required for the circuit.
