How Is Resistance Affected In a Circuit? Introduction For this investigation I will be looking at how resistance is affected in a circuit. There were 4 variables that I could have changed and they are the length, thickness, type and temperature. Length: The longer the wire the greater the resistance. This is because when the wire is increased in length it increases the length the electrons have to travel which will slow down the current giving off a greater resistance. Thickness: The thicker the wire the smaller the resistance. This is because the thicker the wire the more space there is for electrons to flow through creating a greater current and there for having a smaller resistance. Type: The type of wire can affect the size off the resistance as well. There are some wires that are better conductors of electricity than others i.e. copper is a better conductor of electricity than nichrome meaning that nichrome has...
