Is a light bulb an output device?
It can be.
Does a light bulb give off radiant or thermal energy?
THe light bulb emits light while in the process heat in the infrared spectrum is emitted.
Is a light bulb an example of stored energy?
No. A light bulb can only USE energy, it cannot STORE it. Before it can operate it needs to be given a supply of electrical energy and, from that input of energy, it produces outputs of energy in the form of heat and light.
Can you use a 130 volt light bulb on a 120 volt supply?
Yes, in fact that is what a rough service bulb is rated at. The bulb used on a 120 volt system will have a reduced wattage output as to what it would be on 130 volts.
Did people accept the light bulb or did they reject it?
The light bulb was widely accepted and may have been the single most popular invention of all time - although there have since been several alternatives such as the fluorescent tube and the LED, which are in the process of replacing the light bulb.
What is the input or output of the light bulb?
Input to light bulb is Electricity and output is light.
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.
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 diffrence between input and output?
input can only receive while output can only send. For example a light bulb can only receive electricity whilst a socket in the wall can only send electricity.
Is a sensor an input or output device?
It is an input, sensors are always inputs.
Would you expect to find direct or alternating current in the filament of a light bulb in your home the filament of a light bulb in a car the output of a battery charger?
Light bulb in the home - alternating current (A/C) Light bulb in a car - direct current (D/C) Output of a battery charger - direct current Input of a battery charger - usually alternating current
Is a light bulb an output device?
It can be.
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.
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.
What is the effiency of 60watt bulb run on a 100joule?
"60 watts" means "60 joules every second". That's what a '60 watt' bulb is designed to consume. If you put 100 joules of energy into a light bulb, 100 joules of energy are going to come out of it, one way or another. Either that energy will be converted into light and heat by the bulb's filament, or else it won't get consumed at all, and it'll come out the other side of the bulb and still be available for use in some other device. So, comparing output energy to input energy is not an effective way to evaluate the efficiency of a light bulb. What you need to do, in order to compare the economy and effectiveness of light bulbs, is to compare LIGHT output to input ENERGY.
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
