What is the basic unit of capacitance:
The basic unit of capacitance is: f (France), in addition to μ f (micro method), pF (skin), there is also a comparison with fewer units, namely: nF (), due to the capacity of the capacitor is very large, so we see often is μ f, nF, pF units, instead of f units.
Consistent rules in the world, plus 1 volt DC voltage to capacitor, it can store the charge, for the capacitance of the capacitor (the power unit voltage), by the letter c indicates. The basic unit of capacitance farad (f). Under 1 volt DC voltage, assuming a capacitor stores charge of 1 Coulomb, capacity was set at 1 Farrah, Farah with the symbol f, as shown in the 1F=1Q/V. In practice, the use of, the capacitance of the capacitor is usually much smaller than the 1 farad, usually smaller units, millifarad (mF), micro-method (μ f), nanofarad (nF), law (pF), their contact is: 1 micro-method is one out of 10,000 Farah; micro-method 1 method for skin equals one out of 10,000.
