Principle

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.

Benefits


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


Tasks


To connect coils of different dimensions (length, radius, number of turns) with a known capacitance C to form an oscillatory circuit.

From the measurements of the natural frequencies, to calculate the inductances of the coils and determine the relationships between:



inductance and number of turns

inductance and length

inductance and radius
