Function and Applications
Set for simple measurement and recording of equipotential lines of different electrode configurations without electrolytes on electrically conducting paper. This set allows the performance of 5 student experiments about the following topics:

• Electric fields
• Electric field strength
• Inhomogeneous electric fields (dipole fields)
• The electric conductor as an equipotential surface
• Electrostatic tip-shape effect

In all 5 experiments, you can use the Cobra SMARTsense Sensor Voltage instead of the classic meter in combination with tablets and smartphones

Benefits

• The ideal combination of classic experiments (practical competence) and digital data acquisition (media competence)
• Individual teaching structure possible: you can decide to chose the measuring instrument you want (classic or digital)
• Future-proof: Prepare the transition to the digital school today
• Perfectly matched to digital science lessons with tablets and smartphones
• Faster and higher learning success: The use of digital devices increases the identification and thus increases the motivation of the students
• No electrolyte required
• Direct measurement of potential with high resistance voltmeter
• Measuring points can be transferred (pressed through) onto a sheet of white paper during measurement

• Easy teaching and efficient learning through the digital experiment descriptions enclosed as QR codes

Equipment and technical data

• The equipment set consists of all necessary components for the experiments
• Cobra SMARTsense Voltage: Measuring range +/- 30 V, resolution 0.02 V, sampling rate 1000 Hz (10000 Hz via USB)
