Capacitance is a typical characteristic of a capacitor. And is generally expressed by the following formula. Capacitance=εr×ε0×S/d(εr:Relative permittivity of the dielectric, ε0:Permittivity of a vacuum =8.9×10-12[F/m], S:Electrode surface area, d:Dielectric thickness) As the above...
The SI unit of capacitance is farad (Symbol: F). The unit is named after Michael Faraday, the Great English Physicist.A 1 farad capacitor, when charged with 1 coulomb of electrical charge, has a potential difference of 1 volt between its plates....

process. Because the time interval for one degree or radian of a phase is inversely proportional to the wave's frequency (f), you can use that frequency to calculate the time unit that corresponds to a single degree or radian. If working with degrees, you can use this formula: ...
However, a wave's wavelength is directly related to its wave number. In fact, a wave number is sometimes described as the number of wavelengths in a given distance. The wave number can also be defined as the reciprocal of the wavelength, as expressed through the following formula. ...

So this is our target. The formula for the reactance of a capacitor is, XC= 1/2πfc= 1/2(3.14)(50Hz)(C)=47Ω. Solving for the capacitance, C, we get the value of approximately 67μF. So we need a capacitor of at least 67μF to get a resistance of one-tenth the value ...
