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 ...
A paradoxical property of resonant circuits is that they have the ability to produce quantities of voltage or current (in series and parallel circuits, respectively) exceeding that output by the power source itself. This is due to the cancellation of inductive and capacitive reactances at resonance...
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 ...
Respective inductance values connected in series are designated as L11, L12, L21, and L22, respective capacitance values thereof as C11, C12, C21, and C22, an inductance value connected in parallel as 2xLK, and a capacitance value thereof as CK/2. In FIG. 6 loss will be ignored. This ...
where spurious resonances are typically introduced by parallel motional branches, we have found that, depending on the electrical probing spot on the device top electrode and having a capacitive coupling to the bottom electrode, a complete parallel resonator including different series resistance and induc...

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....
Tuned circuit, any electrically conducting pathway containing both inductive and capacitive elements. If these elements are connected in series, the circuit presents low impedance to alternating current of the resonant frequency, which is determined by t
amplifier 12 and controls the rectifier 16 which processes the measured signals sensed by coils 30 and 30' to control device 18. FIG. 2a shows one of two switching circuits. The circuit of FIG. 2a has an rf coil 30 in series with an adjustable capacitor 32 and parallel thereto a ...
