Define reactance X and impedance Z. Can these be nagative ? If yes, when and what does it imply ?`

Answer» For definitions, see text. As `X = X_(L) = X_(C ) =` negative, when `X_(C ) gt X_(L)`, i.e., reactance X can be negative.
It implies, alternating current leads the applied alternating voltage in the circuit. However cannot be negative.
