Ohm's law

Article no: P1372400

Principle

The students should first derive Ohm's law I ∼ U from their measured values. Then they should find out that R = const. is the condition for the validity of this law. To avoid confusion between the words "resistor" (the electrical component) and "resistance" (the physical term), the modules are first referred to as the 50 Ω and the 100 Ω module.

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

Tasks

What is the relationship between voltage and current?

Take a series of pairs of voltage and current measurements in a circuit and use these to determine the relationship between U and I.
