What are the benefits of the light bulb?
Although incandescent light bulbs remain a convenient source of light, as they have been for a long time, they are now an obsolete technology, because there are other sources of artificial light which are much more energy efficient. Fluorescent lighting is more energy efficient, and LEDs are even more energy efficient that fluorescent lighting.
What job does a bulb do in a circuit?
The bulb converts energy from the power source into light and heat. It is the load in the circuit.
What is a light fixture?
A fixture or device that holds a light in place by means of some sort of socket, that is connected to a power source.
What is lumens per watt could you give a brief definition about lumens per watt?
Luminous efficacy is a figure of merit for light sources. It is the ratio of luminous flux (in lumens) to power (usually measured in watts). As most commonly used, it is the ratio of luminous flux emitted from a light source to the electric power consumed by the source, and thus describes how well the source provides visible light from a given amount of electricity.This is also referred to as luminous efficacy of a source.
What wave type is used by digital communications?
In digital communications, a digit is either a one or a zero, or an "on" or an "off" signal. The wave shape that is composed of "on's and off's" is the square wave.
What is a source of digital light?
Light is not naturally digital - perhaps you mean solid state? Digital light as in a fibre-optic cable is just laser light modulated.
Does HDMI cause TV tuner to convert for an external source?
light green
What is a device that uses a light source to read characters marks and codes and then converts them into digital data that a computer can process?
optical reader
Is light a renewable resource of energy?
Light IS energy; it is not a SOURCE of energy. You can convert one form of energy into another, if you need to.
Which device uses light sensing optical equipment to convert images of text drawngs and photos into digital form?
Scanner
What is the sour of energy for producer?
The SOURCE of energy for producers is the sun, plants convert the suns light from light energy to into chemical energy.
How much is 149476000 kilometers in light years?
{| |- | 149476000 km = 0.00001579996 light year source: http://www.convert-me.com/en/convert/length |}
Why do you need light in photosynthesis?
We need light in photosynthesis as Light provides the energy source. The process is based on light. The plants use light to convert energy. The same reason that we need air to breath.
What allows you to write on screen with digital pen and convert to PC info?
A light pen can be used to draw on a computer screen.
What does the sun do for a flower?
The sun is a source of energy for flowers and plants. Plants use photosynthesis to convert light energy into usable energy.
Is light a digital device?
no light is a wave Analog are waves Digital is pulses (1 or 0)
Which device is used to convert analog signals to digital signals?
In datacommunications this is a modulator/demodulator, commonly known as a modem. In electronics a digital to analog converter (DAC) chip is used to convert digital signals to analog and an analog to digital converter (ADC) chip to convert analog signals to digital. Some chips are available which include both ADC and DAC functionality. There are thousands of different types of DAC and ADC sytems and which one to use largely depends on how fast you want to do the conversion.
