By winding the cable in a tight coil, it will act as an inductor (the concept behind dynamos, electric motors etc).
All you need in the ‘magical’ circuit, is an inductor and rectification circuit to produce a relatively substantial direct current.
As I said, the impedance of a capacitor is inversely proportional to its capacitance and the impedance of an inductor directly proportional to its inductance.
Single inductor fully integrated differential voltage controlled oscillator with automatic amplitude adjustment and on-chip varactor
He used an animal ear membrane to receive signals from an oscillating galvanic inductor .
The input and output capacitors and an inductor need to be added on the board to complete a converter design.
In this transform, springs are inductors , masses are capacitors. and dampers are resistors.
The capacitors had charges oscillating, inductors had currents oscillating, all at the same frequency…
Passive components are capacitors, resistors, connectors, filters, inductors , and oscillators.
Several of the inductors were burned out, the solenoid was split, and several of the resistors had broken loose.
