Physics coursework. Aim: My aim of my experiment is find out the factors that effect resistance in a metal. Variables that could effect resistance:> Diameter: Thin wires have less resistance than thick wires. This is because the resistance of the metal has been decreased as the metal has more flow of electrons.> Length: Long wires have more resistance than short wires.> The material used: Iron has more resistance than copper.> Temperature: The hotter the wire the more resistance there is, than cool wires.> The thinner the wire the more resistance there is. Prediction: I predict that the resistance in the metal would decrease, if the metal length were shorter than it would be if it were longer. The resistances in current are called Ohm's. The resistances in metals are proportional to the current sent through the metal. The higher the resistance, the more voltage is required. Resistance is a force that...
