XC ≈ −159.154943 Ω. This is a calculated example under the model stated above; it is not a measured component specification.
Hz, H, F, Ω, S. Convert prefixes before substituting values; keep the input and output units attached to every number.

With Z = R + jX, an ideal capacitor has X < 0 and an inductor X > 0. The sign encodes phase, not negative dissipation.

Reactance X is the imaginary part of impedance Z. Real parts such as winding resistance or capacitor ESR must be added separately.

Not generally. Parasitic capacitance and inductance can reverse the apparent behavior. Use the manufacturer’s impedance curve near self-resonance.
