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.
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:
1.inductance and number of turns
2.inductance and length
3.inductance and radius.
