What is a Schumann Resonance? Believe it or not, the Earth behaves like an enormous electric circuit. The atmosphere is actually a weak conductor and if there were no sources of charge, its existing electric charge would diffuse away in about 10 minutes. There is a 'cavity 'defined by the...
Resonance in a circuit occurs when the energy between two elements of a circuit oscillates. For example, the oscillation of energy between the inductor and capacitor in the LC circuit and RLC circuit. Thus, the resonance frequency is a certain frequency that relie...
Many sources I've read state that reactive power is important because it helps maintain voltage and magnetic fields in inductors, but in a circuit at its resonance frequency, the inductive and capacitive reactances should cancel so there would be no reactive power. What happens in this...
