Inductance of solenoids with Cobra4 Xpert-Link
A square wave voltage of low frequency is applied to oscillatory circuits comprising coils and capacitors to produce free, damped oscillations. The values of inductance are calculated from the natural frequencies measured, the capacitance being known.
- On-the-fly switching of the numerous induction coils for quick and easy experimenting
- Intuitive, touch-optimized software that controls all devices simultaneously
- Simplified implementation: all pre-settings already prepared
- Further experiments in electricity and electronics can be performed with the equipment
