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. The number of free electrons depends on the material and more free electrons means a better conductor‚ i.e. it has less resistance. For example‚ gold has more free electrons than

used with steel‚ or by using an aluminium alloy to help with the mechanical strength that is needed in overhead power lines. Aluminium is a very light metal with a specific weight of 2.7 g/cm3‚ about a third that of steel. Aluminium’s Electrical Resistivity at 20°C is at 2.69 µΩ.cm. Aluminiums conductivity is around 60% that of copper (coppers being 59.6 × 106 S/m). Argon is a colorless‚ odorless‚ tasteless‚ and non-toxic gas. It is a good example of a gas that can conduct electricity. It is an

Utilizing a Strain Gage Circuit to Measure Weight as Function of Changing Resistance John C. Greavu III University of Minnesota‚ School of Physics and Astronomy I. INTRODUCTION Operational amplifiers can be combined with gages to accurately measure mechanical properties as functions of electrical variables of a circuit. Here‚ we used two strain gages on the inside and outside of a load cell to measure the mass of hanging weights as a function of voltage. As the resistance of a wire is proportional
