As Spherical Conductance = 4(pi)Eo r.If u need 1 F then calculate r(radius) u get 9 X 109 which is not possible 2 make..!!!
OR
The capacitance of a conducting sphere of radius R is given by
Hence for the planet earth: about 709 µF
Thus for 1 F the radius is about 140 times greater than earth's radius.
One farad is equal to one coulomb of electric charge stored per volt of potential difference across a capacitor. In simpler terms, a capacitor has a capacitance of one farad when it can store one coulomb of charge for every volt applied across it. This unit is named after the physicist Michael Faraday.
Farad
A capacitor meter measures the value of a capacitor in pf (picofarads), nf (nanofarads), uf (microfarads) or even farads. There are a million uf in a farad, 1000 nf in a uf, and 1000 pf in a nf. A farad is a very large amount of capacity. The capacity tells you how much energy the capacitor can store from a voltage source.
Capacitors are built to different specifications depending on application. The higher the capacitance the more charge the capacitor can store.The capacity to store electric charge, when a voltage is applied. Measured in Farad = Coulomb/Volt. In other words, if for every volt applied the capacitor stores 1 coulomb of charge, it would have a capacitance of 1 farad. In practice this is a huge unit, and the capacitance is usually expressed in micro-, nano-, or even pico-Farad.
farad is the unit for capacitance in SI system. If one volt is developed as one coulomb charge is placed then capacitance has to be one farad. But one farad is enormous large one so practically speaking we use only micro farad, nano farad and pico farad. They are respectively 10-6 F, 10-9 F and 10-12 F
I read that it 500 rms to 1 Farad.
A Farad is the electrical unit of capacitance. Many commonly used capacitors (also known as condensors) are measured in micro-Farads (μF). A micro-Farad is one millionth of a Farad. To convert from micro-Farads to Farads, divide the micro-Farad value by one million. 2 micro-farads = 0.000002 Farads.

The SI unit of capacitance is the farad. 1 farad is 1 coulomb per volt.
The Farad is a measure of how much electric charge is accumulated on the capacitor. Named after Michael Faraday
about 500 uF
Farad is the basic unit for capacitance. The MFD is an abbreviation for microfarad, which is one-millionth of a farad. The capacitance of a 50 MFD capacitor is one 50 millionth of a farad.
