Measurement of voltage with Cobra SMARTsense

Principle

After the students have become acquainted with the term voltage and its unit, they should learn how a voltmeter must be connected and what must be taken into consideration when making a measurement.In addition, they should recognise that an electrical instrument or appliance must be supplied with its rated voltage for proper operation.

Benefits

• 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

• Future-oriented teaching: Integration of sensors (Cobra SMARTsense) into digital science education

Tasks
