Can broaden our definition of a ‘resistor’ to include anything you put into the circuit—a wire a motor even a hot dog with this broader definition of a resistor, let’s ask this question: “is electrical resistance” background to your experimental approach: electrical resistance for the objects that you test you. Links to physics: current and resistance are an integral part of the electronic industry need for complete electronic knowledge an example includes the microscope, where a background in electronics and optics would be the wire resistance goes up with the higher wire temperature 8 the wire glows due to the excited metal electrons. How the length of a wire affects its resistance in my physics coursework i am going to investigate the effect of the length of a wire on its resistance resistance is the measure of how easy it is for current to flow through a wire.
Brush up on some basic electrical theory and deepen your knowledge about electricity in this post we cover ohms law, ac and dc current, circuits and more / understanding basic electrical theory this leaves us with the letter r which represents resistance electrical resistance, measured in ohms, is the measure of the amount of. How the length of a wire affects its resistance in my physics coursework i am going to investigate the effect of the length of a wire on its resistanceresistance is the measure of how easy it is for current to flow through a wire current is the rate of flow of charge through a conductor, and it is measured in amps using an ammeter to help me plan my investigation i have completed a. What is resistance the electrical resistance of an object is a measure of its opposition to the passage of an electric current it is a property of the material that restricts the movement of free electrons in the materialit determines the size of the electric current passing through the material. First published in 2008 ref: 00094-2008dvd-en voltage, energy and power in electric circuits.
Physics gcse coursework: resistance of wire aim: to investigate if the length of wire affects its resistanceprediction (hypothesis): i predict that the longer the wire the higher the resistance, and the shorter the wire the lower the resistanceknowledge: resistance is that property of electric components that turn electric energy into heat in opposing the passing of an electric currentit. Modern dry cell construction uses a steel can connected to the positive (raised) contact the negative connection is the centre of the base with an annular ring of insulator between it and the can. Stephen lucas salters horners a2 physics coursework 1 what affects the range of a trebuchet by stephen lucas stephen lucas salters horners a2 physics coursework the fulcrum will consist of a brass wire with a constant diameter of 29 x 10-3m, in addition the background physics behind this type of. An investigation into the resistance of a wire - hubpages free gcse physics coursework essays an investigation into the resistance of a wire noticed that if you double the length of the wire, the resistance is roughly physics coursework investigating resistance of wires and its physics coursework investigating resistance of wires and its nichrome length (mm) voltage(v) current.
Physics coursework resistance of a wire background knowledge. Background ohm’s law is an known cross-sectional area of the wire to calculate the resistivity resistance versus the cross-sectional area of the wire tighten both clamps to secure the wire in place 3 ohm’s law move the reference probe of the wire-slider apparatus to the “0 cm” mark move the slider. Later wire b takes on to a higher resistance than wire b but in the end the last reading conveys that wire b has a slightly more higher resistance than wire a the amount of resistance in both the wires do not show any patter or does not follow a trend, however it makes it explicit that wire b has more resistance than wire a science. Gcse coursework resistance of a wire contains articles that reproduce discussions to study how the resistance of a wire is overstated by the size of wire article regarding resistance of a wire coursework depicts to observe how the resistance of a wire is exaggerated by the size of wire.
I am trying to do my physics coursework to do with resistance in wire however i am really struggling to do the risk assessment i have no idea what the risk's of using nichrome wire are thanks. Best answer: 1) you can't use an ohmeter to measure 'r' in the presence of the emf if you have access look up the experiment for measuring the emf and 'r' of a battery: set up stable illumination of the light cell and keep it constant. Physics sph1d1 - winter 2010 factors affecting resistance of wire lab analysis 2 pages enthalpy change lab controlled variables factors affecting resistance of wire lab background knowledge viewing now i was behind on tulane coursework and actually used ucla’s materials to help me move forward and get everything together on time. Physics investigation of resistance aim: to investigate how the electrical resistance of a wire changes in relationship to it├é┬┤s length gcse physics physics investigation of resistance aim: to investigate how the electrical.
Gcse physics coursework - resistance of a wire coursework resistance of a wire task to investigate how the resistance of a wire is affected by the length of the wire. Gcse coursework resistance of a wire has articles or blog posts that replicate discussions to look at how the resistance of a wire is exaggerated because of the size of wire guide concerning resistance of the wire coursework depicts to look at how the resistance of a wire is exaggerated via the size of wire. I’ve just started teaching my second lot of year 12 students the new (aqa) physics a-level i believe the move from coursework / assessed practicals in the form of empas etc is a positive one but, like many colleagues, i’m still finding my way when it comes to the best approach to take to ensure the best outcomes for my students. An investigation into the resistance of a wire - gcse physics 30 dec 2016 free gcse physics coursework essayfor example, when the length of the wire is 20cm the resistance is 314 ohms when the length of the resistance of a wire - physics coursework gcse - gcse resistance of a wire - physics coursework gcse extracts i shall investigate how the length of a wire affects its resistance.
