The voltage across the capacitor is now roughly equal to the applied voltage, and it is in phase with it. Since X L < X C, the phase angle for the current in the circuit is negative.. If we increase the frequency above the resonant frequency, X L (= ωL) increases and X C (= 1/ωC) decreases.At 503 kHz, X L is about 9.48 kΩ, and X C is about 1.44 kΩ. The …

capacitor
On subject of using different size capacitors in parallel, this has a side-effect of creating an impedance spike as the inductances and capacitances of different components resonate. It may or may not matter but you''re not damping that particular frequency much if at all.

Resonance and Tuning Methods
mechanical tuning capacitor. The induc- tance value of the coil is not changed in this arrangement. Rather, the capacitor is ad- justed to change the resonant frequency of the coil-capacitor combination. At each setting of the capacitor, we will have resonance (canceled reactance) at a different frequency within the adjustment range of the ...

filter capacitor in this role. The current pulses charging the capacitor when the diode(s) are forward-biased are generally much briefer than the time the capacitor is discharging into the load. Due to the principle of Charge Conservation in a capacitor, these pulses are therefore quite a bit higher in amplitude than the load current.
8.2: Series Resonance
Looking first at the phase (blue, left axis), we see in both cases that high (Q) circuits exhibit a quick transition from a negative (capacitive) phase angle to a positive (inductive) phase angle. We also notice that the phase shift hits zero at (f_0), implying unity power factor. The impedance magnitude plots show a slightly different story.

Electrical resonance
Resonance of a circuit involving capacitors and inductors occurs because the collapsing magnetic field of the inductor generates an electric current in its windings that charges the capacitor, and then the discharging capacitor provides an electric current that builds the magnetic field in the inductor. This process is repeated continually. An analogy is a …
Types of Capacitors : Working and Their Applications
The comparisons between the different types of capacitors are generally made with regards to the dielectric used between the plates. Some capacitors look like tubes, small capacitors are often constructed from ceramic materials and then dipped into an epoxy resin to seal them. So here are a few of the more common types of capacitors available.
Measuring capacitance :: Electronic Measurements
The phase difference between the capacitor voltage and the voltage cross the reactance is than circa 45 °. This means that the measure frequency must be very high in some cases, tens to hundreds …
Reason of phase difference!
But if we start using an AC waveform to rapidly charge and discharge the capacitor we get this interesting phase shift. What happens is in a sinus wave the voltage does not change at a constant rate. And the faster you try to charge or discharge a capacitor, the more current you would need. It just so happens that the place in a sine …
Electrical resonance
Resonance of a circuit involving capacitors and inductors occurs because the collapsing magnetic field of the inductor generates an electric current in its windings that charges the capacitor, and then the discharging capacitor provides an electric current that builds the magnetic field in the inductor. This process is repeated continually. An analogy is a mechanical pendulum, and both are a form of simple harmonic oscillator.
Understanding the Operation of Quartz Crystal Oscillators
Below f s, the crystal acts as a capacitor, and the phase shift from X 1 and C 1 is near 0 . At f s, the crystal has resistive impedance and this phase shift is about 90°. Above f s, the crystal exhibits inductive behavior, and the phase shift can be close to 180°.
Electronics/Capacitors
As well, it should be noted that placing two 100 V capacitors in series results in the same as having one capacitor with the total maximum voltage of 200 V. This, however, is not recommended to be done in practice, especially with capacitors of different values. In a capacitor network in series, all capacitors can have a different voltage over ...

A Balancing Act: Tools and Considerations to Keep Voltage in Line
Capacitors have constant impedance; increasing capacitor voltage increases capacitor current proportionally, raising voltage across conductor inductance. Capacitors on a low-voltage phase generate less leading current, producing less voltage rise-in effect, slightly amplifying voltage unbalance.
