Calculation of Reactive Resistance

Reactive Resistance – electrical resistance to alternating current, caused by energy transfer by the magnetic field in inductors or by the electric field in capacitors.
Elements with reactive resistance are called reactive.

Calculation of inductive and capacitive resistance is performed using formulas:
XC=1/(2π×F×C); XL=2π×F×L, where
XL - Inductive Resistance, (Ohm)
XC - Capacitive Resistance, (Ohm)
F - Signal Frequency, (Hz)
The calculation will only be valid for sinusoidal current.
To calculate any parameter, two other values must be entered.


Units of Measurement for Calculating Capacitance:

kHz, nF, Ohm
MHz, pF, Ohm

Units of Measurement for Calculating Inductance:

kHz, mH, Ohm
MHz, μH, Ohm
