• ## What Factors Affect the Current Flowing Through a Wire?

I am going to investigate how the resistance of the wire affects a current flowing through a wire. I know that as resistance changes, current changes, as Ohm's law: I = V/R. If one part of an equation changes, the equal must be done to the opposite side. To detect how resistance affects current, I must first discover what factors affect resistance. These factors are: * Length of the wire - if a wire is

• ## 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

• ## 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
