A larger capacitance value results in a higher capacitive reactance, while a smaller capacitance value corresponds to a lower capacitive reactance. The relationship between capacitance and capacitive reactance is described by the same formula: 𝑋𝑐=12𝜋𝑓𝐶 X c =2 π f C 1, where 𝑋𝑐 X c is the capacitive reactance, 𝑓 f is the frequency, and 𝐶 C is the …

AC Capacitor Circuits | Capacitive Reactance And Impedance
If the reactance of the capacitor is larger than the resistance of the resistor, θ will be closer to 0 degrees. If the resistance is much larger than the reactance θ will be closer to 90 degrees. In the parallel RC circuit, we do not find impedance through a vector sum of circuit resistances.

Difference Between Resistance and Reactance
Key Differences Between Resistance and Reactance The resistance is the obstacle in the flow of current in an electrical circuit due to resistor. While reactance is the opposition to the charging current due to either inductor or capacitor. Resistance is the property associated with both ac and dc circuit. both ac and dc circuit.
Capacitive Reactance | Basic Electronics Learning Guide
Reactance is also inversely proportional to the value of capacitance (C), i.e. the value of X C at any frequency will be less in larger capacitors than in smaller ones. All capacitors have infinitely high values of reactance at 0Hz, but in large capacitors, the reactance falls to a low level at much lower frequencies than in smaller capacitors.

Reactance The flow of current through the circuitry has an inductor or capacitor. A larger value of reactance caused to make less value of voltage given. Reactance is like resistance and has some differences that not lose power like resistance. Reactance is used

OverviewComparison to resistanceCapacitive reactanceInductive reactanceImpedanceSee alsoExternal links
In electrical circuits, reactance is the opposition presented to alternating current by inductance and capacitance. Along with resistance, it is one of two elements of impedance; however, while both elements involve transfer of electrical energy, no dissipation of electrical energy as heat occurs in reactance; instead, the reactance stores energy until a quarter-cycle later when the energy is returned to the circuit. Greater reactance gives smaller current for the same applied voltage.

Impedance
Impedance is the opposition to current in an AC circuit. It is a combination of the resistance from resistors, and reactance from capacitors and inductors. In other words, the resistance doesn''t change because of the sinusoidal waveforms of the voltage and current.
