A level physics coursework resistance of a wire

Gold Member goku said: Yes it is, I can try and see what other non-metals my school has which i can use to find the specific heat capacity of. I have done a little experiment on finding the specific heat capacity of an aluminium block. The mass of the block is weighed with a pair of scales.

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

A level physics coursework resistance of a wire

The number of free electrons depends on the material and more free electrons means a better conductor, i. For example, gold has more free electrons than iron and, as a result, it is a better conductor.

The free electrons are given energy and as a result move and collide with neighbouring free electrons. This happens across the length of the wire and thus electricity is conducted. Resistance is the result of energy loss as heat. It involves collisions between the free electrons and the fixed particles of the metal, other free electrons and impurities.

These collisions convert some of the energy that the free electrons are carrying into heat. How is it measured?

The resistance of a length of wire is calculated by measuring the current present in the circuit in series and the voltage across the wire in parallel.

These measurements are then applied to this formula: This means that the resistance of a metallic conductor is constant providing that the temperature also remains constant. Furthermore, the resistance of a metal increases as its temperature increases.

This is because at higher temperatures, the particles of the conductor are moving around more quickly, thus increasing the likelihood of collisions with the free electrons.Regardless of your deadline, budget, specifications, or academic level, we can provide immediate help for your physics resistance GCSE coursework essay, term paper, book report, research paper, dissertation, thesis, or university coursework.

Jul 04,  · Best Answer: For what level is this coursework? The relationship between resistance and the length of a wire has been a GCSE "favourite" for years.

At GCSE, I would happily accept that the increase in resistance is due to increased collisions - I wouldn't expect any regardbouddhiste.com: Resolved. Physics coursework Aim to see how the resistance of a wire changes with the length of the wire. Also does the colour etc affect the resistance as well.
