An electric light bulb becomes hot to the touch primarily due to the conversion of electrical energy into heat energy as the electric current passes through the filament. This resistance in the filament generates heat, which in turn causes the bulb's surface to warm up. Additionally, the glass components of the bulb can also retain heat, contributing to the overall temperature increase. As a result, touching a lit bulb can lead to burns or discomfort due to this heat.
What else can I help you with?
What does the electric light bulb do to illuminate a room?
The electric light bulb produces light by passing electricity through a filament, which causes it to glow and emit light. This light fills the room, allowing us to see and navigate in the dark.
Which came first the telephone or the electric light bulb?
The electric light bulb came first but was patented later that the telephone was.
What is a electric bulb in short?
a bulb is light bulb
How does electric light work?
Electric lights work by passing an electric current through a filament or gas inside the bulb. The current causes the filament to heat up and emit light, or the gas to produce light through a process called electroluminescence. The light is then emitted out of the bulb through a transparent covering.
When you turn on a lamp and the light bulb becomes warm which energy conversion causes this heating of the light bulb?
Electrical energy absorbed by the lamp's filament produces thermal energy as well as light.
What does a light bulb have to do with an electrical light source?
A light bulb is a source of electric light. In an incandescent light bulb, the glass bulb forms a protective shield around a glowing filament. The air inside the glass bulb is removed, or replaced with an inert gas. Electric current is passed through a thin metal filament (usually tungsten), which causes it to glow white hot, giving out light. The protective bulb stops the filament from burning up, as it has no Oxygen.
Why a lighted electric bulb connected to the main should not be touched?
do not touch alighted electric bulb conncted to the main
What is the Function of light bulb in an electric circuit?
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
When was the first electric light bulb used?
where was the first light bulb used
What does electric light bulb look like?
it look's like a mini light bulb and you usally use them in an electric circuit
What is the energy conversion for an electric bulb?
An electric bulb converts electrical energy into light energy and heat energy. When electricity flows through the filament of the bulb, it heats up and emits light as a result of the high temperature. Some of the electrical energy is also converted into heat energy, making the bulb hot to the touch.
What energy forms can electric light bulb make?
A light bulb can make heat and light.
