Everything CCEA students need to know about how to conduct an investigation into the resistance of a metallic conductor.

To investigate experimentally how the resistance of a metallic conductor at constant temperature depends on length and obtain sufficient values to plot a graph of resistance (y-axis) and length ...

Contact resistance is that amount of resistance to current flowin the contact surface or juncture of a composite material or leads of a devicethat contributes to the total resistance of a circuit. You ...
