Capacitive reactance calculator

Online calculator for formulas used in electronic circuit design and electrical engineering.

Basic electric calculations:

Ohm's Law, Ohm's Law with power, DC power, AC real power, LC resonant frequency, Capacitor charging/discharging, Capacitive reactance, Capacitive current + reactive power, Capacitor energy, Capacitor Δ energy, RC discharging, Inductor square pulse, Inductive reactance, Inductive current + reactive power, Inductor energy, 2 parallel resistors, 3 parallel resistors, System bandwidth

Wire and winding calculations:

Diameter ↔ cross section ↔ AWG, Wire resistance, Wire weight, Current density, Wire R thermal drift

Calculate Capacitive reactance: 1uF, 50Hz, kΩ


This calculation can calculate the capacitive reactance XC of a capacitor knowing its capacitance and the frequency. You can also calculate the capacitance knowing the desired reactance and frequency, or calculate the frequency knowing the capacitive reactance and capacitance.   XC = 1 / (2πfC)

Enter any 2 values, the 3rd one will be calculated:

Capacitance: -0.1 +0.1 -1 +1 -10 +10 -100 +100
Frequency: -0.1 +0.1 -1 +1 -10 +10 -100 +100
XC: -0.1 +0.1 -1 +1 -10 +10 -100 +100

Capacitive reactance formula says:

•The capacitive reactance (Xc) of a 1uF (one microfarad) capacitor at 50Hz (fifty hertz) is 3.183098861838kΩ (three point one eight three zero nine eight eight six one eight three eight kiloohms).
•For a 3.183098861838kΩ (three point one eight three zero nine eight eight six one eight three eight kiloohms) capacitive reactance at 50Hz (fifty hertz), you need a 1uF (one microfarad) capacitor.
•A 1uF (one microfarad) capacitor would have a 3.183098861838kΩ (three point one eight three zero nine eight eight six one eight three eight kiloohms) reactance at 50Hz (fifty hertz) frequency.
