The capacitor increases the initial susceptance by j0.7, moving us from the -j0.5 to j0.2 constant-susceptance arc. The new admittance, y 2, is at the intersection of the g = 0.2 constant-conductance circle and the b = 0.2 constant-susceptance arc, as shown in the above figure.
As the frequency increases the reactance decreases. The capacitive susceptance is defined as the reciprocal of the reactance. It is measured in Siemens. Just as we resistance which is a measure of opposition to the flow of current, we have capacitive susceptance that is a measure of a purely capacitive circuit’s ability to pass current.
As frequency increases, reactance decreases, allowing more AC to flow through the capacitor. At lower frequencies, reactance is larger, impeding current flow, so the capacitor charges and discharges slowly. At higher frequencies, reactance is smaller, so the capacitor charges and discharges rapidly.
The interaction between capacitance and frequency is governed by capacitive reactance, represented as XC. Reactance is the opposition to AC flow. For a capacitor: where: Capacitive reactance XC is inversely proportional to frequency f. As frequency increases, reactance decreases, allowing more AC to flow through the capacitor.
At higher frequencies, reactance is smaller, so the capacitor charges and discharges rapidly. In DC circuits, capacitors block current due to infinite reactance. But in AC circuits, capacitors pass current easily at high enough frequencies. The voltage and current are out of phase in an AC capacitance circuit.
At lower frequencies, reactance is larger, impeding current flow, so the capacitor charges and discharges slowly. At higher frequencies, reactance is smaller, so the capacitor charges and discharges rapidly. In DC circuits, capacitors block current due to infinite reactance.
The answer lies in the interaction between the inductive and capacitive reactances. Expressed as impedances, we can see that the inductor opposes current in a manner precisely opposite that …
