Measurement Of Low Resistances For Electrical Lab Training Workshop.
Principle The resistances of various DC conductors are determined by recording the current / voltage characteristic. The resistivity of metal rods and the contact resistance of connecting cords are calculated. Tasks To plot the current / voltage characteristics of metal rods (copper and aluminium) and to calculate their resistivity. To determine the resistance of various connecting cords by plotting their current / voltage characteristics and calculating the contact resistances. What you can learn about Ohm's law Resistivity Contact resistance Conductivity Four-wire method of measurement
