• ## Resistance of a Wire

Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Resistance is a 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. The circuit itself can resist the flow of particles if the wires are either very thin or very long. e.g. The filament across an electric light

Theory behind my experiment Thickness (cross sectional area of the wire), length, and temperature all have some effect on the amount of resistance created in a wire. Another factor is the conductivity of the material we are using. Some metals are just more electrically conductive than others. As long as I use the same type of metal for each wire, my experiment will remain fair. Cross Sectional Area The thicker the wire, the less resistant

• ## Resistance of a Piece of Wire

Planning In this piece of coursework, I am going to investigate what affects the resistance of a piece of wire. Wire is made up of atoms. Electric current is a flow of electrons, and it is these electrons that collide with the nucleus of the atoms. Every time this happens, it causes resistance. The build up of friction is what produces the heat. There are many variables that could affect the resistance of the piece
