G.C.S.E Science Investigation How does the length of the wire affect the resistance? The investigation is about how a piece of wire can affect the resistance. I'm trying to find out, if the resistance will change and why if there is a different length of metal/wire, Nichrome. Resistance is like a constriction in the flow and it's the pressure has to work against. So if the voltage is increased the move current will flow but if you increase the resistance less current will flow (because of the pressure has to work against). The current in the metal wire is carried by electrons. These electrons move through the wire but as there is obstruction in the wire, the electrons move past the obstruction but produces friction. This causes the wire to heat up and vibrate. I will use amp meter, volt meter, power pack, connecting leads, Metal/wire and a ruler. ...
