Antoine Allen The effect of the length of a piece of wire has on its resistance Aim To find out how the length of a piece of wire affects is resistance. Background information Conducting materials such as metals have resistance. They oppose the flow electrons through them. Resistance - This is a measure of how hard it is for the electrons to travel through a part of the circuit (measured in Ohms (?)-From S-cool.co.uk Resistance is the force, which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. Resistance is measured in ohms. A resistor has the resistance of one ohm if a voltage of one volt is required to push the current of one amp through it. Resistance occurs when the electrons travelling along the wire collide with the atoms of the wire. These collisions slow down the flow of electrons causing...
