Whats a device that changes electrical energy into light energy?
a light bulb
What kind of energy lights a light bulb?
A light bulb is not energy, but is a device that uses electrical energy to create electromagnetic energy in the form (in part) of visible light and heat.
Which device uses heat to produce light?
Light bulbs. The filament in the bulb is heated in order for it to glow and produce light. This can be considered as a conversion of energy where heat energy is being transferred in light energy.
What device converts electrical energy into heat and light energy?
An incandescent light bulb would be a prime example.
Which household heating device produces both heat and light?
A radiant heater, or an infra-red light bulb, a ceramic hob.
Is sensor an input or output device?
Assuming that a sensor (any type, heat, light, sound etc) is connected to something - eg a computer or a switch etc. it is an 'input' device. The device which created whatever is being 'sensed' is an output device. For example if you put a thermometer next to a light bulb to see how hot it is then the bulb is 'output' and the thermometer is 'input'.
What is the input or output of the light bulb?
Input to light bulb is Electricity and output is light.
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.
WILL 103 VOLTS LIGHT A 60 WATT LIGHT BULB?
Yes, a 103 volt source will light a 60 watt light bulb. The relationship of the bulb's wattage output at a lower voltage, as to the normal voltage that the bulb is rated to operate on, the light output will be lower.
Is lights a input or output?
Light Pen is an input Device.
What is the difference between a spotlight bulb and a flood light bulb?
The spotlight bulb has a different pattern cut into its lens that concentrates the light output into a tight central pattern. A floodlight lens pattern distributes the light output to a larger outside diameter there by spreading the light into a wide flood pattern. The spotlight has a higher light intensity output than the floodlight output.
Is a LED an input or output?
In Light Emitting Diodes when electron jumps from one state to another state it emits some energy in the form of light. And the light will be different for different type of semi conductor materials used for making for it. So, in conclusion Light in LED is a result of output process.
Is a light pen a input or output?
Light Pen is an input Device.
Is a light pen a input output?
Light Pen is an input Device.
Is a sensor an input or output device?
It is an input, sensors are always inputs.
What is the device that converts electrical energy in to light energy?
The light bulb.
How does a change in the size of a current affect the light output of a bulb?
The bulb has resistance which then gets smal
