Understanding Reactance Units
Reactance is the opposition to alternating current (AC) caused by inductors and capacitors, measured in ohms (Ω). Unlike resistance, reactance depends on frequency and creates a 90° phase shift between voltage and current.
Inductive reactance (XL) increases with frequency and is calculated as XL = 2πfL, where f is frequency and L is inductance. This opposition leads the current, making inductors useful for blocking high-frequency signals.
Capacitive reactance (XC) decreases with frequency and follows XC = 1/(2πfC), where C is capacitance. This opposition lags the current, making capacitors effective for blocking low-frequency and DC signals.
In AC circuit analysis, total reactance X = XL - XC determines the reactive component of impedance. At resonance, XL = XC, minimizing total impedance and maximizing current flow.
Reactance calculations are essential for filter design, power factor correction, and resonant circuits in electronics, power systems, and RF applications across various frequency ranges.
