A capacitor is an electronic component that stock power or which varies the oscillation This capacitance storage is expressed in Farads (F), Microfarads (µF), Nanofarads (nF), or Picofarads (pF). There are 3 kinds of capacitors. There are ceramic capacitors, polarized capacitors and adjustable capacitors.

If you want to calculate a time with capacitors base, follow the following formula: T = R X C (T = time in seconds, R = Resistance in ohms, C = Farads)

Example :

With a 100 K resistor (100 000Ω) and a 100uF capacitor, what is the basis for time?

100 000 X 0.0001 = 10

Answer : 10 seconds

From left to right :

- Ceramic capacitor (Mistake on the picture)

- Polarized capacitors

- Variable capacitors

When you have 2 capacitors in series, we use the following formula:

When there are 3 capacitors in series, we use the following formula:

When you have 2 capacitors or parallel more, it uses the following formula:
