Reactance is the property of an electrical component to oppose the change in current while impedance is the combination of resistance and reactance. There are two types of reactance: Capacitive & Inductive
Capacitor's reactance Capacitor's impedance Cartesian form: Polar form: ZC=XC∟-90º Capacitor types Variable capacitorVariable capacitor has changeable capacitance Electrolytic capacitorElectrolytic capacitors are used when high capacitance is needed. Most of the electrolytic capacitors are polarized ...

with L. Capacitance, meanwhile, is resistance that occurs when a device such as acapacitorstores an electric charge that resists changes in voltage. Capacitance is measured in farad (F) and symbolized with C. A circuit's reactance can result from inductance, capacitance or a combination of ...
How is cable derating factor calculated? Selection of cable – Case #2 Current capacity of 95 Sq.mm cable is 200 Amp, Resistance = 0.41 Ω/Km and. Reactance = 0.074 mho/Km. Total derating current of 70 Sq.mm Cable = 200 · 0.93 = 187 Amp. ...
XC→ Reactance of the capacitorω→ Radiant frequencyj→ Imaginary unitHere, the divider’s voltage ratio isRC → Time constant of the circuit represented as τ. Voltage Divider Under Loaded Condition Now, we can see the voltage divider circuit in a loaded condition. Here, the resistors (R1 ...
Why is decoupling necessary? Decoupling provides a low-impedance path from the power supply to the ground. Therefore, choosing a low-inductance but high-value capacitor (low impedance) is very important. Effect of capacitive coupling on the current return path. ...
The reactance of a capacitor indicates the amount of opposition to current flow, but unlike resistance, the amount of opposition depends on the frequency of the signal passing through the capacitor. Thus, we have to calculate reactance at aspecific frequency, and the equation that we use for ...
affectschangingcurrent, reactance is specific to AC power and depends on the frequency of the current. When reactance is present, it creates a 90 degree phase shift between voltage and current, with the direction of the shift depending on whether the component is an inductor or a capacitor. ...
