The comparison of parallel and serial resonance circuits has been made and the power loss mechanism in both cases has been studied. A power supply based on serial resonant circuit of plasma source has been developed.*ELECTRIC DISCHARGES关键词: Meetings Electric discharges Barometric pressure Symposia ...
Therefore, a parallel LC circuit has a maximum impedance at the resonance frequency. The series resonant circuit has a minimum impedance at the resonance frequency. So, the impedances of series and parallel LC circuits at resonance are opposites. As a consequence of the peak in the impedance ...
In the above circuit, we have a 10 µF capacitor and a 100 mH inductor. Since we know the equations for determining the reactance of each at a given frequency, and we’re looking for that point where the two reactances are equal to each other, we can set the two reactance formula ...
This invention is not only applicable when the same coil array is used for parallel transmit, receive and shim, but also when two separate coil arrays are used. In that case, the B 0 shimming capability can be integrated into one of the coil arrays (i.e. a transmit array with B 1 ...
If these elements are connected in series, the circuit presents low impedance to alternating current of the resonant frequency, which is determined by the values of the inductance and capacitance, and high impedance to current of other frequencies. In a parallel-connected tuned circuit, the ...

Lagrangian of the complete system, we provide an analytical expression for the linear response function for the motion in the case of a mechanical resonator and the current for the case of an electromagnetic resonator, thereby considering the influence of the resonator on the spin and vice versa....
employed in a variety of applications. One use for resonance is to establish a condition of stable frequency in circuits designed to produce AC signals. Usually, a parallel (tank) circuit is used for this purpose, with the capacitor and inductor directly connected together, exchanging energy betwe...
