Factors affecting Resistance Plan: The Task of this investigation is to find out the factors that affect the resistance of a wire. This will be done by performing experiments that try and investigate different proposed factors and to see whether they affect the resistance. 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 requires 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 resistance. Resistance is a measure of how hard it is to move the electrons through the wire. Wire length: If the length of the wire is increased then...
