Abstract:
     The capacitor with mutual capacitance belongs to the area of electric field theory and capacitor technique. When there is a common area in which the electric fields of the two capacitors, exist it is to say that there is mutual capacitance between the two capacitors. The capacitor with mutual capacitance is generally made by rolling up several laminated layers of electrode plates and dielectrics. There are more than two terminals outside the capacitor. If there are mutual capacitances between capacitors A and B and between capacitors B and C, the voltages across the two terminals of A and C respectively are then mixed and appear at the two terminals of B. The capacitor with mutual capacitance can find its use in detecting controlling, signal mixing, low-pass and anti-interference. It can be used as a step-adjustable capacitor with mutual capacitance and an adjustable capacitor as well.
