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.
Why does energy saver give more light than electric bulb of same volt?
First of all, it is not volts that counts, but watts. Watts indicate how much you will pay for your electricity bill. (watts, multiplied by the time you have it on, actually - watts is a unit of power.) Of course, you can't create energy from nothing. What really happens here is that the traditional incandescent light-bulb is extremely wasteful - 90% or 95% of the energy gets converted to heat. The fluorescent light wastes less, but there is still room for improvement.
Why the energy saver bulb is coiled?
To have enough bulb or surface area to produce the required amount of light.
What is a great power saver product?
The single most important power saver product of the last 20 years is the energy saving light-bulb. They use 1 fifth to 1 third of the energy of a conventional light-bulb and last 6000 to 15000 hours compared to 750-1000.
Does an energy saver coiled bulb continue to flicker when switched off?
no
Why does energy saver give more light than electric bulb of same watt?
Both bulbs output the same amount of energy. The difference is in how much of that energy is output as heat vs the energy output as light. In a standard incandescent light bulb about 10% of the energy is output as light while the other 90% is output as heat. This makes the bulb only 10% efficient. For a florescent bulb the output of light is about 50% and the other 50% is output in heat. This means that a fluorescent bulb outputs five times as much light for the same wattage as a standard incandescent bulb, hence you can get the equivalent of 100 watts of light output for only 20 watts of electricity.
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.
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.
What is most of the energy produced by a light bulb?
Most of the energy in a light bulb is heat energy.
What energy occurs in the light bulb?
light and heat energy occur in a light bulb when it is turned on.
