You are to write a resistance of a wire coursework, aren’t you? A question may arise – are you next A. Einstein? Do not laugh. Why not? You are going to investigate a serious topic. Even Einstein needed some coursework help.
 
Let us start with the following:

1. The aim of your resistances of a wire coursework: to investigate what factors influence the resistance of a wire. Thus, for instance, you can mention such factors as length, temperature, material, voltage, etc;
2. The theoretical part of your resistance of wire courseworks:
   • What is resistance? It is a degree which is measured when an object is opposed to an electric current.
   • How can it be measured? You are to know that the resistance of a wire can be measured with the help of the formula: R=V/I, where R- resistance, I- current, V- voltage (electric tension).
3. An indispensable part of your resistance of a wire coursework is the understanding of Ohm’s Law, which points out that the current, when passing through a wire, becomes proportional to voltage at a constant temperature. This means that V and I are constant variables, and the resistance of a wire remains constant on condition that the temperature is constant. Thus, the resistance of a wire depends directly on the temperature. When the temperature rises, the particles start moving around much quicker, thereby they increase the possibility to collide with free electrons.

4. The resistance of a wire coursework should meet all the requirements;
5. You can consult your supervisor as for his/her personal requirements for the resistance of a wire coursework.
6. You can ask your teacher to help you with the experiment for the resistance of a wire coursework.
7. You had better not reject any help, because performing an experiment is an important part of your resistance of a wire coursework.

Hope that now you have a better idea of what your resistance of a wire coursework should be about.
