Reaktanskalkylator

Kapacitiv eller induktiv reaktans vid en given frekvens.

Introduktion

Reactance Calculator — Capacitive or inductive reactance at a frequency. Enter Reactance type, Frequency (Hz), C (F) or L (H) to get an instant, accurate result.

Formel

Reactance opposes alternating current and depends on frequency. Capacitive reactance is Xc = 1 / (2πfC), while inductive reactance is X_L = 2πfL, where f is frequency, C is capacitance, and L is inductance.

Steg för steg

  1. Enter the Reactance type.
  2. Enter the Frequency (Hz).
  3. Enter the C (F) or L (H).
  4. Click Calculate to see your result instantly.

Verkligt exempel

Example: With Reactance type = capacitive, Frequency (Hz) = 60, C (F) or L (H) = 0.0001, the Reactance Calculator gives Reactance Ohm: 26.5258.

Vanliga Frågor

What is the difference between capacitive and inductive reactance?
Capacitive reactance (Xc) decreases as frequency increases, since capacitors pass higher-frequency AC more easily. Inductive reactance (X_L) increases with frequency, since inductors oppose rapid current changes more strongly.
What units does reactance use?
Like resistance, reactance is measured in ohms (Ω), even though it arises from capacitance or inductance rather than resistive losses.
How is reactance different from resistance?
Resistance dissipates energy as heat, while reactance stores and releases energy without net dissipation, causing a phase shift between voltage and current in AC circuits.
What inputs does the Reactance Calculator need?
You'll need to provide: Reactance type, Frequency (Hz), C (F) or L (H). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Reactance Calculator?
The Reactance Calculator applies the formula exactly as calculated — Reactance opposes alternating current and depends on frequency. Capacitive reactance is Xc = 1 / (2πfC), while inductive reactance is X_L = 2πfL, where f is frequency, C is capacitance, and L is inductance. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Reactance Calculator free to use?
Yes, the Reactance Calculator is completely free, requires no signup, and runs instantly in your browser.

Om Reaktanskalkylator

The Reactance Calculator uses a real, verifiable formula — Reactance opposes alternating current and depends on frequency. Capacitive reactance is Xc = 1 / (2πfC), while inductive reactance is X_L = 2πfL, where f is frequency, C is capacitance, and L is inductance. — so results are accurate every time, not an approximation.
