• ## Resistance of a Wire

Theory What is resistance? Electricity is conducted through a conductor, in this case wire, by means of free electrons. The number of free electrons depends on the material and more free electrons means a better conductor, i.e. it has less resistance. For example, gold has more free electrons than iron and, as a result, it is a better conductor. The free electrons are given energy and as a result move and collide with neighbouring free

• ## What Factors Affect the Resistance of a Wire?

What Factors Affect the Resistance of a Wire? Planning Background Electricity flows around a circuit in a current. A current is the flow of electrons. Currents are measured in amps. Voltage is the force which pushes electricity through a wire. Voltage comes from a cell or a socket. Voltage is measured in volts. Electrical resistance is a measure of the degree to which a body opposes the passage of an electric current. (en.wikipedia.org/wiki/Resistance(electricity). Resistance is

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

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
