Incandescent lamps are classified according to the shape of the bulb and the type of service, as well as the size and style of the base. How are incandescent lamps rated?
AI Explanation
The correct answer is A) operating voltage and wattage.
Incandescent lamps are rated based on their operating voltage and wattage, which are the key factors that determine the lamp's performance and energy consumption. The voltage rating indicates the supply voltage the lamp is designed to operate on, while the wattage rating specifies the amount of electrical power the lamp consumes. This information is essential for selecting the appropriate lamp for a particular application and ensuring safe and efficient operation.
The other answer choices are incorrect because they do not accurately describe how incandescent lamps are typically rated. Resistance, frequency, impedance, and reactance are not the primary factors used to classify and rate incandescent lamps.
