It is possible to repair the variable capacitor in accordance with various circumstances appropriately. Still, its primary faults are the collisions between the moving and fixed pieces, leakage static induction, loose moving pieces, and incorrect moving piece positioning.
As the motion piece of the dual variable capacitor is installed on the axis of the same root, the two groups of capacitance can be adjusted at the same time when the rotating shaft is rotating. (3) the quadruple variable capacitor quadruple variable capacitor consists of four sets of variable capacitors, which consist of four variable capacitors.
1. The capacitor that can be adjusted is called a variable capacitor. The variable capacitor can be divided into air medium and organic film medium according to different media. According to the different structure, it can be divided into single variable capacitor ,double variable capacitor and quadruple variable capacitor.
The capacitors with the capacitance value are fixed are known as ‘Fixed Capacitors’. Similarly, the capacitors that are with varying amounts of capacitance are known as Variable Capacitors. This type of capacitor has the capability of changing the values of its capacitance either “Electrically” or “Mechanically”.
Learn about variable capacitors, essential parts of many electronic devices. Adjustable capacitance makes these capacitors essential for fine-tuning electronic circuits.
Differential variable capacitors have two independent stators, but unlike in the butterfly capacitor where capacities on both sides increase equally as the rotor is turned, in a differential variable capacitor one section's capacity will increase while the other section's decreases, keeping the sum of the two stator capacitances constant.
