Question

Write a note on Paper Capacitors​

Answer 1

Answer:

Paper capacitor is also known as a Fixed capacitor, in which paper is used as a dielectric medium, that stores energy in the form of the electrical field. These capacitors are used at power line frequency with a capacitance value of 1nF to 1uF. It stores a fixed amount of electric charge.

Answer 2

Answer:

Definition: Paper capacitor is also known as a Fixed capacitor, in which paper is used as a dielectric medium, that stores energy in the form of the electrical field. These capacitors are used at power line frequency with a capacitance value of 1nF to 1uF. It stores a fixed amount of electric charge.

A paper capacitor is made up of two metallic plates with a dielectric material paper between them. It has positive and negative plates. When a small amount of electric charge is applied over the plates, the positive charge is attracted to one plate and a negative charge is attracted to another plate. This electrical energy is stored in the form of the electrical field. This stored electrical energy is used by the discharging of a capacitor. These are available in the range of 500pF to 50nF. These offer high leakage currents. The capacitance  of the paper capacitor measured in terms of Farad’s(F). The capacitance range of this capacitor varies from 0.001 to 2.000 microfarad with a high voltage range of upto 2000V. Initially, the paper is used between the two aluminum sheets as a dielectric medium. But, now other materials like plastic are also used. These capacitors are available in the range of 300 picofarads to 4 microfarads with a working voltage of 600 volts.
