Measurement Of Low Resistances.
Measurement Of Low Resistances 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
Four-wire method of measurement
Measurement Of Low Resistances - 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.
