Analysis of Energy Processes That Precede Resonance in an Electric Circuit

Abstract: It is shown that, when an electrical circuit R, L, and C is connected to a sinusoidal voltage power supply, inductance L and capacitance C accumulate the magnetic and electrical energies necessary for resonance during the transient process and always receive some energy from the external space. As a result, the final inductance and capacitance energies become equal and correspond to the unified energy of the subsequent steady sinusoidal (resonant) process known from the classical theory. Therefore, electrical resonance is impossible without the energy relations of inductance and capacitance with space. © 2023, Allerton Press, Inc.
