Power out put of a light bulb

Extracts from this document...


Power out put of a light bulb Light Basic Light is a form of energy that can be released by an atom. It is made up of many small particles, these particles are called light photons. They are the most basic units of light. Atoms release light photons when their electrons which are the negatively charged particles that move around an atom's nucleus, becomes excited. ...read more.


The wires and the strings are contained in a glass bulb, which is filled with still gas, such as argon. When the bulb is hooked up to a power supply, an electric current flows from one contact to the other, through the wires and the string. As the electrons move along through the string, they are continuously bumping into the atoms that make up the string. ...read more.


a light bulb In this experiment we set up a circuit by connecting a light bulb to a power output via a voltmeter and an ammeter. We then measured the voltage and the amps varied with the potential difference. When we had found the volts and amps we were able to work out resistance and the power output. We then drew two graphs, measuring the resistance varied with the potential difference and the power output varied with the potential difference. ?? ?? ?? ?? ...read more.

    How does the power dissipated by a light bulb vary with voltage?

    5 star(s)

    This will ensure that the test is fairer because if I use different bulbs, then they could have different resistances. For example, if I use another light bulb, then the tungsten may be longer and so the electrons will have to flow along a longer distance, thus losing more energy,

  2. How does current vary with voltage in a light bulb?

    This is Ohm's law. All alloys obey ohms law as long as the temperature is constant. Ohmic and non Ohmic conductors Here are some Ohmic and none Ohmic conductors; A resistor is a none Ohmic conductor because it has a resistance which increases slightly when the temperature rises.

    In order to continue ensuring that the test was indeed fair, I used the same equipment as I did for the first part of the results. I followed the safety and fair testing requirements as strictly as before. Results (Part ii): Voltage (V)

    If a person touches it, then it will burn them. They can be used to produce all different coloured light by placing different filters. The life time of the bulb is reduced by constant use of the bulb Industrial/commercial The halogen light bulb is used in industries to light up the areas of work.
