reactance

of: a reactive circuit component in an a.c. circuit

is: the impedance of the circuit component. [P5.4]

has the symbol: [P5.4]

has as its SI unit: the ohm [P5.4]

generally depends: on the angular frequency of the alternating current

is exemplified: for a capacitor, by the reactance [P5.4]

is exemplified: for an inductor, by the reactance [P5.4]
