Resistance of a wire (GCSE corsework)

Does Increasing the Length of a Nichrome Wire Affect its inverse? Introduction In this experiment I am departure to see conditions the heaviness of cable impart affect the electric automobile underground of a wire. I will also be seeing weather different lengths of wire effect the wearance of the wire. I will be setting up the wire to a go and will be using a ammeter and volt round to record my results. Background information galvanizing ongoing is a go of electrons a yearn a conductor like a metal wire. The electric cell function-up-and-goes the electrons round the rotary. Break the overlap and the electrons can non flow. Electric latest is not used up because electrons are not destroyed. lightness bulbs enhance light because they have high protection and resist the flow of the electrons. The legitimate is measured in amps using an ammeter. potential divagation provides push to drive the current round the circuit; potential difference is measured in v olts. In a series circuit the potential difference supplied by the electric battery is divided up between chemical elements in the circuit. enemy is a measure of how hard it is to get a current to flow through a share at a particular potential difference or voltage. Each component in a circuit has a resistance.

Prediction I look that if I increase the length of the wire, then the resistance will increase. I also forecast as the thickness of the wire is increased the resistance will decrease, I think this because An electric current flows when charged particles called electrons move through a conductor. The mov ing electrons can collide with the atoms of ! the conductor. This makes it more difficult for the current to flow, and causes resistance. Electrons collide with atoms more often in a want wire than they do in a short wire. A... If you look at to get a full essay, order it on our website: OrderCustomPaper.com
