In a transistor, a small change in the base current causes a large change in the collector current. In this experiment, the relationship between the collector current and the base current is examined, and the control characteristic graph plotted. 

The current amplification factor of the transistor can be determined from the slope of the characteristic curve.


  • No additional cable connections between the building blocks needed - clear arragned and quick setup
  • Contact saftey due to puzzle blocks system
  • Corrosion-free gold plated contacts
  • Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside


Can a transistor be used as an amplifier?

Examine the dependence of the collector current of an npn transistor on the base current at a constant collector voltage of 12 V.
