Capacitor Variable (Variable and Trimmer)

Variable capacitors and trimmer is a type of condenser whose capacity can be changed. Condenser is subject to change due to the physical capacity to have a shaft that can be played using a screwdriver.

  Variable capacitor (Varco) is made of metal, has a maximum capacity of approximately 100 pF (pikoFarad) to 500 pF (100pF = 0.0001μF). Condenser with variable antenna spool and spool serves as a voter wave oscillator certain frequencies to be captured.

While the trimer capacitor in parallel with a variable capacitor serves to fine tune the frequency of the wave election tersebut.Kondensator trimer has a capacity below 100 pF (pikoFarad).
