What else can I help you with?
How you can calculate how much energy is used by a light bulb?
from its power if it is 100 watt so it produces 100 joule per second but this includes all energy produced by the lamp (light/heat energy) Their is a formula E=h x v, E=energy, v=frequency, and h=the constant I think
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 does 40 watts bulb mean?
An electrical watt is a measure of power. A 40 watt light bulb uses 40 watts of electrical power. It has a relative measure of twice the light output of a 20 watt bulb and one half the output of an 80 watt bulb. A 40 watt bulb uses 40 Joules of energy each second, or 40 watt-hours of energy each hour. In 1000 hours it uses 40 kilowatt-hours or Units of electrical 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.
What is the formula to calculate how much a light bulb uses?
The formula to calculate the energy usage of a light bulb is Power (Watts) x Time (hours) = Energy Used (Watt-hours). For example, a 60-watt light bulb used for 5 hours would consume 300 Watt-hours of energy.

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.
What powers a light bulb?
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
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.
What form of energy does a light bulb?
A light bulb converts electrical energy into light energy and heat energy.
Is a light bulb an energy source?
No.it uses energy sources (electrical energy to light up
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.
What 2 forms of energy does a light bulb give out?
A light bulb gives out light energy and heat energy as forms of energy. The light energy is emitted as visible light, while the heat energy is generated as a byproduct of the bulb's operation.
