Principle

The electrical conductivity of copper and aluminium is determined and the Wiedmann-Franz law is tested.

Benefits

  • Easy and precise measurement of the electrical conductivity
  • Compact, easily transportable setup

Tasks

  1. Determine the electrical conductivity of copper and aluminium by recording a current-voltage characteristic line.
  2. Test of the Wiedmann-Franz law.

Learning objectives

  • Electrical conductivity
  • Resistivity
  • Wiedmann-Franz law
  • Lorenz number
  • Four-point measurement
