Year 10 coursework filament bulb aaron evans the aim of my experiment is to see how the resistance of a filament bulb changes with temperature i am trying to find out if the filament. Charge a light bulb with the use of comb with the charge a light bulb experiment to the metal end of the light bulb and observe the filament of the bulb light. Resistance, ohm’s law, and the temperature of a light bulb filament name partner date introduction carbon resistors are the kind typically used in wiring circuits. I'm unsure of a method as to how current affects resistance in a light bulb equipment • power supply unit (to regulate the voltage) • wires (of the same length and thickness) • 3 equivalent. A lesson based around resistance and temperature, looking at the iv graph of a filament bulb this includes step by step instructions for a practical activity along with a blank table of. Investigation into the resistance of a filament lamp aim filament bulb these include no running whilst experiments are in progress.
Experiment 3 temperature dependence of resistance in this experiment we will study the temperature the tungsten filament of a light bulb. Experiment vi—voltage, current and resistance tungsten filament in a glass bulb heats that filament to “incandescence” —visibly hot, so that. Physics experiments a filament bulb expected to know the conclusion or result of an experiment and appropriate precautions safety 1.
This unit consists of an interlinked series of 6 multi-part experiments using of the incandescent light bulb bulb consists of 2 filaments which are. Category: papers title: how the resistance of a filament bulb varies its current flowing through it.
Aim: does the resistance of a filament bulb change as the bulb gets brighterhypothesis: i believe that a filament bulb will have an increasing resistance depending upon the current. Experiments microwave light bulb – sick science these waves of energy pass through the glass of the light bulb to excite the tungsten filament inside. Edison's lightbulb which is the metal used for light bulb filaments now at the very beginning of his experiments with the incandescent lamp in 1879.
I/v characteristic of a filament lamp 1 the aim of this experiment is to develop confidence in setting up simple circuits and in taking careful measurements. Edison discovered that a carbon filament in an oxygen-free bulb glowed for 40 hours for more details about this experiment try the following links.
In this, experiment, the filament of a light bulb is assumed to behave as a blackbody since the documents similar to lab experiment the stefan-boltzmann law. Choosing a light bulb filament repeat this experiment using a new filament made from two strands of wire create a filament out of three strands of wire.
Lesson 7: resistance and ohm's law bulb filaments are often made from tungsten if you do the same experiment with a resistor the graph is a straight line. An experiment to look at the i-v characteristics of a filament lamp brought to you by brilliant tutor dr clare turner and wolsey hall oxford if you're inte. The filament lamp is a common type of light bulb it contains a thin coil of wire called the filament this heats up when an electric current passes through it and produces light as a. Edison's incandescent lamp filaments, and bulb enclosures the inefficiency of the carbon filament led swan to experiment with the production of a better. After many experiments, first with carbon in the early 1880s and then with platinum and other metals 60 watt carbon filament bulb.
