Q

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?

🔍 Key Concepts

• Incandescent lamp basics: how light is produced by a heated filament • Common nameplate information found on light bulbs (what you normally see printed on them) • Difference between electrical rating (what the lamp is designed to operate at) and other electrical properties like resistance or reactance

💭 Think About

• Think about what information you need to know to safely connect a lamp to a circuit without damaging it or having it burn out too quickly • Consider what two values you usually specify when you buy or replace a household or navigation light bulb • Ask yourself which option reflects the conditions the lamp is DESIGNED to run at, instead of a property that just happens to result from those conditions

✅ Before You Answer

• Check which choice matches the two main numbers you commonly see printed on a bulb (for example, household or navigation light bulbs) • Make sure the option you choose describes operating conditions, not just an electrical characteristic that could change with those conditions • Eliminate answers that involve quantities you do NOT normally see printed on consumer or marine lamp labels, such as reactance or impedance
