At a frequency of 85.0 Hz, the reactance of a capacitor with a capacitance of 3.80106 F is 492.8 Ω.
X = 1/ C [tex]\omega[/tex] where [tex]\omega[/tex] is angular frequency
Where C = Capacitance = 3.80×10−6 F
[tex]\omega[/tex] = angular frequency = 2\πF
= 2(22/7)85
= 534 rad/s
Therefore X = 1/[3.80×10−6 F x 534]
= 492.8 Ω
By building up electric charges on two nearby surfaces that are isolated from one another, a capacitor is a device that stores electrical energy in an electric field. It is a two-terminal passive electronic component. Capacitance is the name given to a capacitor's effect. A capacitor is a thing, not a thing with a unit. The capacitor's capacitance is defined as the ratio of the charge held in either of its conductors to the potential difference between them. Farads are used as the SI unit for capacitance.
