lt is to be demonstrated that a coil in an alternating current circuit has, alongside its ohmic resistance, an additional resistance that can be changed to a geat extent by a variable iron core in the coil.
- 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
