Question
______ of power consumed by Incandescent bulbs gets wasted in the form of heat.
Open in App
Solution
The correct option is B 60%
An incandescent light bulb, incandescent lamp or
incandescent light globe is an electric light with a wire filament heated to
such a high temperature that it glows with visible light (incandescence). The
actual power consumed (in watts) and the apparent power (in volt-amperes) is
equal. 60% of power consumed by Incandescent Bulbs gets wasted in the form of
heat. Incandescent light bulbs are
usually marketed according to the electrical power consumed. This is measured
in watts and depends mainly on the resistance of the filament, which in turn
depends mainly on the filament's length, thickness, and material. For two bulbs
of the same voltage, type, color, and clarity, the higher-powered bulb gives
more light.
