A light bulb uses electrical energy, and produces light, as well as heat.
light energy
Because the light form the bulb produces heat witch produes thermal energy.
To plug it in, you use your muscle energy. When current flows through the bulb,electrical energy converted to the heat and light energy in the bulb.
Light, of course, since that's what the light bulb is designed to produce. There is also waste energy, as heat, and (to a small extent) as sound.
The energy to produce the light stops and the light stops.
light energy
It uses less energy to produce the same amount of illumination as a standard light bulb
Because the light form the bulb produces heat witch produes thermal energy.
The energy used by a lightbulb in kWh can be calculated from the voltage across the bulb, the current through the bulb, and the number of hours of operation of the bulb. energy = voltage * current * hours / 1000
Bulbs convert an electrical energy to produce light
Luminescence
To plug it in, you use your muscle energy. When current flows through the bulb,electrical energy converted to the heat and light energy in the bulb.
Light, of course, since that's what the light bulb is designed to produce. There is also waste energy, as heat, and (to a small extent) as sound.
The energy to produce the light stops and the light stops.
Electricity can be converted to light using light bulb. An incandescence light bulb produce light by passing electricity through filament (resistance) and create heat so hot that it radiate out light. It also can produce light using Electro-luminescence effect as in LED lamb or using ionized gas discharged as in Fluorescent lamb.
To have enough bulb or surface area to produce the required amount of light.
Heat and light. Sometimes sound, too.
