Medición de resistencias pequeñas

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

  1. To plot the current / voltage characteristics of metal ...

Leyes de Kirchhoff

Principle

First Kirchhoff's laws are verified by measuring current, voltage and resistance in series and parallel circuits. The Wheatstone bridge circuit is used to determine unknown resistances more precisely.

Tasks

  1. Verify Kirchhoff's laws by measuring current and voltage ...

Termogenerador semiconductor

Principle

In a semi-conductor thermogenerator, the no-load voltage and the short-circuit current are measured as a function of the temperature difference. The internal resistance, the Seebeck coefficient and the efficiency are determined.

Tasks

  1. To measure no-load voltage U0 and ...
