Diodes as rectifiers with Cobra SMARTsense

Principle

A diode allows current to pass only in one direction and blocks it in the other. In an AC circuit, current can flow through a diode only during a half-wave.

Benefits

• Particularly comprehensible and didactically prepared description of the experiment (reference to everyday life, etc.) incl. protocol questions.
• Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
• Increased motivation among students through use of the intuitive measureAPP.
• Increased media literacy.
• No additional cable connections between the modules necessary - clearer and faster set-up.
• contact safety due to puzzle-like interlocking building blocks.
• Hard gold-plated, corrosion-resistant contacts
• Double learning success: electrical circuit diagram visible on the upper side and real components on the lower side

Tasks

Investigate the effect of a diode in a direct and an alternating current circuit.

Learning Objectives

Students should learn about the rectifier effect of a diode.
