Series Resonance In series RLC circuits, resonance occurs when the total series impedance is minimized at the resonant frequency. This creates a bandpass filter effect around this frequency. Series DC Motors DC motors have the field and armature windings connected in series. This results in high st...
As long as no additional electrical load is applied to such circuits, the response is 6dB/octave (which means that the signal level drops by 6dB for every octave below the filter's 'turnover' frequency), or 'first order'. These simple, passive circuits cannot be used to boost frequencies,...

This is a process of collecting data at the atomic level by using sensor technology that can detect changes in motion, electric and magnetic fields. Quantum sensing has been used in magnetic resonance imaging, or MRIs, and provides faster results and improvements in resolution quality. ...
If the appropriate capacitance is added so that the loops resonate at the same frequency, the amount of induced current in the receivers increases. This is resonant inductive charging or magnetic resonance; it enables power transmission at greater distances between transmitter and receiver an...
Tesla coil (Tesla Ciol) is a transformer using the resonance principle (resonance transformer), invented by the SerbiAn-American scientist Nikola: Tesla in 1891, it can obtain millions of volts of high-frequency voltage, is also a distributed parameter high-frequency series resonant transformer. Mai...
To completely understand the working of PCB antennas, one must have some knowledge of Impedance matching and resonance circuits. In simple terms, to achieve maximum efficiency, the source impedance and load impedance must have to be equal.
