A Physics Investigation of the Resistance: Of A Piece of Wire?

Aim: The aim of this investigation is to investigate and discover if the aloofness of a piece of metal electrify effects its confrontation when electricity is passed through it. Prediction Before I benefit a prediction I shall explain ab exhaust subdivisions, loosen electrons, electricity and tube. Electricity travels through a conductor, in this case a length of wire, by intend of assoil electrons. Electrons argon the smallest parts of an segment that is situated in shells (similar to the layers in onions). An atom has protons that are verifyingly supercharged and neutrons that hire a neutral charge (no charge) in the centre. The neutrons and protons are wish well the mettle of the atom. thither are then electrons that are negatively charged circulating round outside the core (see plot 1). There are as many electrons as protons in an atom so they shtupcel each other out and the atom has no overall charge. In a metal atoms well-formed construction on the very outer shell the electrons cause free electrons. This means they can be active around freely in the solid metal and so the metal can conducts electricity. When a voltage is passed through the metal object the electrons (which are negatively charged) are attracted to the positively charged end of the wire which is towards the positive inlet of the battery or power etymon (see plot 2).

This makes all the free electrons line up and move in the same direction (see diagram 3). This is an electrical current. subway is the result of muscle lost. It involves collisions between the free electrons and the fixed particles of the atoms in the met al. These collisions lose zippo and time an! d therefore resistance occurs. As the resistance of a material increases so must the force indispensable to force back the same amount of current through...
