Principle

Determine the current strength flowing through a semi-conducting diode. Determine the collector current with the collector voltage for various values of the base current intensity.

Benefits

• Fast and easy experimenting
• Get to know the behaviour of several types of semiconductors
• Detailed experiment guide with extensive explanations and step-by-step instructions
• Measure voltage and current simultaneously on four channels
