Principle
In this experiment, self-induction is investigated - a property of coils in which a voltage is generated by changing the current. This counteracts the change in current and leads to a time delay when switching on and off.
Tasks
- What effect does a coil have when closing a DC circuit?
- Investigate the voltage across a resistor connected in series with a coil.
Learning objective
The aim of the experiment is to learn that when a coil is switched on, a self-induction voltage is created which counteracts the increase in current.
Advantages
- Simple setup in just a few minutes.
- High resolution data acquisition (up to 10 kHz).
- Improved media competence.
- Safe student power supply (RiSU-compliant).
