Resistance of a wire course work

Explain the difference between resistance and resistivity. Version. For Teachers. Teacher Tips. Overview of sim controls, model simplifications, and insights into 2 Lei de Ohm no" Resistance in a Wire (HTML5)" Artur Arajo Cavalcante e Gilvandenys Leite Sales: MS Other HS: GCSE Physics Coursework Investigation of the resistance of a wire The resistance (measured in ohms?

) is opposition to the flow of an electric current: the greater the resistance in a circuit, the more energy is needed to Like the resistance to water flow, the total amount of resistance to charge flow within a wire of an electric circuit is effected by some clearly identifiable variables. First, the total length of the wires will effect the amount of resistance. The longer the wire, the more resistance that there will be.

Apr 19, 2012  Furthermore, if you double the length of the wire, the resistance is roughly doubled. For example, when the length of the wire is 20cm the resistance is 3. 14 Resistance in a Wire Coursework 1540 Words Apr 2nd, 2012 7 Pages In this investigation we are trying to look for resistance in a piece of wire, and how the length of a wire can increase or decrease the resistance. 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.

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. 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. The problem with using resistance as a measurement is that it depends not only on the material out of which the wire is made, but also the geometry of the wire.
