What else can I help you with?
When the light bulb is lit electrical energy is changed into light energy and?
When lighting a light bulb, it is changed into light and heat/thermal energy.
What is the starting and finishing energy of a light bulb?
Zero,because the distance has no affect to convert electric energy into light energy.
A bulb in a lamp converts electric energy into?
A bulb in a lamp converts electric energy into light and heat energy.
If electrical energy goes into a light bulb what useful energy comes out?
The useful energy that comes out of a light bulb is primarily in the form of light and heat. The electrical energy is converted into light energy that illuminates the surroundings and heat energy that warms up the light bulb and its surroundings.
Is potential energy what a light bulb uses?
NopeNo, potential energy would be, for instance, a spring that is compressed. It could cause motion if released. It is stored energy. The light bulb uses electrical energy, which it converts to light and heat energy. potential energy is like when you wind up a torch or a radio
When a light bulb is glowing which form of energy goes into the light bulb?
Electrical goes in. Electromagnetic (heat and light) come out.
Where does the energy powering a light bulb ultimately come from?
The Sun.
What waste energy come from a light bulb?
Mainly heat.
What type of energy is when you plug in a light bulb?
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.
Where does the energy given off by the light bulb come from?
From the electric current that powers it.
When a light bulb is glowing which form of energy goes into the bulb Which form of energy leave it?
The energy that goes in is electrical energy; the energy that leaves it is visible light, as well as heat.
When energy runs through a light bulb what kind of energy does the light bulb produce?
A light bulb uses electrical energy, and produces light, as well as heat.
Is a light bulb an energy source?
No.it uses energy sources (electrical energy to light up
What form of energy does a light bulb?
A light bulb converts electrical energy into light energy and heat energy.
What transformations occur in a light bulb?
In a light bulb, electrical energy is transformed into light energy and heat energy.
Why is a low energy light bulb described as more efficient than a normal light bulb?
Because efficiency is measured in Output/input. At the same light bulb output, one with lesser energy input required is higher in efficiency. Possible confusion come from description of low energy light bulb without stated the high or low energy is compared at what lux it can produce light.
What is most of the energy produced by a light bulb?
Most of the energy in a light bulb is heat energy.
