Ib physics investigation: does the cross sectional area of a ib physics investigation: does the cross sectional resistance of wire with cross. Resistance decreases if the cross-sectional area is increased this sometimes confuses people, as it's not obvious look at these two pieces of metal: the narrow wire has fewer paths available for the electrons to move through. Electricity the resistance of wires - material does the resistance of a wire depend on its material nearly all wires in a circuit are made of metal because metals are good conductors of electricity.

Resistance graphs current-potential difference graphs take a graph where the current flow is shown on the vertical axis and the potential difference is. Unit b753: physics controlled assessment and calculating the resistance of a wire (p4c) as graph paper). Wire resistance essay examples 13 total results wire conductivity testing of copper an analyis of the resistance of a wire and the way it can be affected by. Before starting my coursework i have decided to choose a factor that will affect the resistance of a wire as it would allow me to lot a graph of resistance.

American wire gauge an approximation for the resistance of copper wire may be wire gauge comparison chart iec 60228, the metric wire-size standard used in. An investigation into the resistance of a wire - gcse physics dec 30, 2016 resistance of a wirefree gcse physics coursework essayi will investigate how the length of the wire affects the resistance. This means that the resistance in a wire increases as: this is called ohm's law the graph shows what happens to the current and voltage when a resistor follows.
