Ohm's law

 Product 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 ? and the 100 ? module.

Task

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.
