Which converts electrical energy to light for general illumination, such as a bulb?

• A. Lighting lamp
• B. Heater
• C. Indicator lamp
• D. Motor

Answer: (A)

For general illumination, you need a device that converts electrical energy into visible light to light up a space. A lighting lamp is designed for that purpose, turning electric power into light energy so the area is illuminated. Inside, the light can come from a filament heating up in incandescent lamps, from gas discharge in some types, or from LEDs in modern lamps—all aimed at producing useful light over a broad area. The other items are different: a heater uses electricity to generate heat, an indicator lamp is a small signal light for status indications, and a motor converts electrical energy into motion. So, the lighting lamp best fits the goal of providing general illumination.
