Understanding Capacitive Reactance with Formulas
In order to split the applied supply voltage, as per the ratio of R2 to the total of R1 and R2 (R2 / (R1 + R2)), these circuits use two resistors (R1 and R2) connected in series. As a result the output voltage (Vo) will equal half of the source voltage (Vs) when R1 and R2 have identical values. ... a capacitor with low reactance makes it ...

AC Capacitor Circuits | Capacitive Reactance And Impedance
The reactance of a 0.1 μF capacitor as the frequency is varied can be seen in Figure 3. As frequency is changed to 50, 100, 1000, and 5000 Hz, each reactance is computed using the formula for capacitive reactance (capacitor impedance). Notice how the reactance on the graph approaches zero as the frequency heads toward infinity. Figure 3. As ...

The graph in Figure 23.43(b) starts with voltage at a maximum. Note that the current starts at zero and rises to its peak after the voltage that drives it, just as was the case when DC voltage was switched on in the preceding section. When the voltage becomes negative at point a, the current begins to decrease; it becomes zero at point b, where voltage is its …
Reactance, Inductive and Capacitive | Physics
Capacitors favor change, whereas inductors oppose change. Capacitors impede low frequencies the most, since low frequency allows them time to become charged and stop the current. Capacitors can be used to filter out low frequencies. For example, a capacitor in series with a sound reproduction system rids it of the 60 Hz hum.

At low frequencies, the phase angle (q) of impedance is around –90°, so the reactance is capacitive. The capacitor frequency response has a minimum impedance point at a self-resonant frequency (SRF), which is determined from the capacitance and parasitic inductance (Ls) of a series equivalent circuit model for the capacitor.
