Physics coursework resistance of a wire safety

Class practical A simple investigation of the factors affecting the resistance of a wire. high currents will cause the safety cutout on the power packs to automatically switch it off. If short lengths of wire are used with relatively high currents and voltages, then significant electrical heating may also occur.

Institute of Physics 76 Apr 19, 2012  I will investigate the resistance of a wire in relation to its length. Prediction. I predict that the longer the wire, the larger the resistance. This is because the free electrons in the wire bump into more atoms, thereby making it harder for Jan 08, 2009 Basically i am studying how length affects the resistance of a wire and i have initially completed this project but i am just show more I am currently doing my Physics coursework and i was just wondering if you could help me get a bit more scientific information on why things occured and happened the way they did.

Physics Coursework Objective: My objective in this experiment is to investigate one of the factors that affect the resistance of a piece of wire; the one I am investing is the length at constant temperature.

Physics Gcse Coursework: Resistance of Wire Physics GCSE coursework: Resistance of wire Aim: To investigate if the length of wire affects its resistance. Prediction (Hypothesis): I predict that the longer the wire the higher the resistance, and the shorter the wire the lower the resistance.

Resistance of a Wire 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. Theory What is resistance. Electricity is conducted through a conductor, in this case wire, by means of free electrons.

One can wire up a doorbell if they use safety precautions, follow instructions, and the proper materials to wire it with. 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. Theory What is resistance? Essay Writing Guide. Learn the art of brilliant essay writing with help from our teachers. Learn more Apr 12, 2005  For the resistance of a wire coursework, i have already done it based on experimenting with different lenghts against resistance.

for the evaluation, i need to write an extension on the coursework: i have a few ideas already Experimenting with other types of materials of wires to see if they Physics GCSE coursework: Resistance of wire Aim: To investigate if the length of wire affects its resistance. Prediction (Hypothesis): I predict that the longer the wire the higher the resistance, and the shorter the wire the lower the resistance.
