chip capacitors are a shiny deduction in physics

The definition of electric capacity has a potential: we have great physical capabilities. Mind (you can fill it with this, in the absence of a transmission loop, eliminate the leakage and self-discharge effect to save it emotionally, obviously it may always exist, its characteristics), widely, it is, in the field of electric power Indispensable electronic components. Mainly used for power drive, signal signal, signal, etc.

The unit of international capacitance is C. (pF) (Pifa native subtle method) and so on.

The conversion relationship is:

1 Farad (F) = 1000 millifarads (mF) = 1000000 microfarads (μF)

1 microfarad (μF) = 1000 nanofarad (nF) = 1000000 picofarad (pF).

The relationship between capacitance and battery capacity:

1 volt-ampere hour = 25 farads = 3600 joules

1 farad = 144 joules

For a motor, if the electric difference between the two stages is 1 volt when the potential energy of the 1 library is used, the electric capacity of this electric power is the 1 method, that is: C=Q/U but the size of the capacitor is not determined by Q (charged electricity) or U (voltage) ) Is determined, namely: C=εS/4πkd. Among them, ε is a constant, S is the opposite rectangle of the capacitor plate, d is the distance of the capacitor plate, and k is the capacitance force constant. Common parallel plate capacitance, capacitance (ε is the dielectric constant between the plates between the plates, C=εS/d. (ε is the dielectric constant between the plates between the plates, d is the dielectric constant between the plates between the plates distance).

Definition C=Q/U

The electric potential energy calculation formula of the motor: E=CU^2/2=QU/2=Q^2/2C

Capacitance calculation formula: C=C1+C2+C3+…+Cn

Total calculation formula: 1/C=1/C1+1/C2+…+1/Cn

Total heat C=(C1*C2*C3)/(C1*C2+C2*C3+C1*C3)
