Notes on using the capacitor
1 / Parameters:
Unit: Farah, referred to as method (F), micro-method (uF), skin method (pF)
1 method = 1 × 1,000,000 microfarads; a micro-method = 1 × 1,000,000 PF
Error: Ⅰ 5%; Ⅱ 10%; Ⅲ 20%

4. Capacitor device points:
Keep away from heat
Prevent a short circuit
Note polarity
Good deal of work before welding
Series and parallel capacitors
a. Capacitors and even, pressure does not increase the capacity to increase
C = C1 + C2 + C3 ... ...
b. Capacitor in series, pressure increased, the capacity decreases
C = 1 / (1/C1 +1 / C2 +1 / C3 + ... ...)
Summary
1. It is an energy storage device.
2. It is not the voltage across the mutation.
3. It through AC, DC isolation.
4. The smaller the capacitor capacity through more high-frequency signal; larger capacitance capacitor, low-frequency signals on the health of the capacitance smaller plants.
5. Choose to use the capacitor, the capacitor voltage, it used to be √ 2 times the voltage.
