Reactance Calculator Reactance Calculator Calculate either the inductive or capacitive reactance of an element. Step 1: Enter Circuit Details Reactance Type Inductive Reactance (\(X_L = 2\pi f L\)) Capacitive Reactance (\(X_C = \frac{1}{2\pi f C}\)) Frequency (\(f\)) (Hz) Inductance (\(L\)) (H) Calculate Reactance Calculated Reactance Reactance (\(X\)): Recalculate
