In the case of mechanical spring oscillation, a periodical change takes place
between potential and kinetic energy (potential energy and motive energy).
Analogous to this, electrical and magnetic field energy changes in the case of
A comparison of mechanical and electrical values is provided by:
• Deflection x
• Load m
• Friction constant k
• Spring constant D
Reciprocal of capacitance 1/C Fig. 11.1.1: Comparison of mechanical and electrical oscillations 156 © Festo Didactic GmbH & Co. KG • FP 1110 11. Physical fundamentals The LC resonant circuit Electromagnetic oscillations are created in a so-called LC resonant circuit consisting
of a coil and a capacitor. Once the capacitor is loaded, it discharges via the coil.
During this process, current intensity and voltage change periodicall...
