the capacitor and its associated resistor set the time constant.
The function of a CVT is to provide a secondary voltage to equipment that is a direct ratio of a much higher primary voltage. They can also be used to couple communication signals onto transmission lines.
A plastic capacitor is an electronic component that stores and releases electrical energy, utilizing a dielectric material made from plastic. Its primary function is to filter, decouple, or smooth out voltage fluctuations in circuits, improving signal quality and stability. Plastic capacitors are known for their reliability, stability, and resistance to moisture and temperature variations, making them suitable for various applications in electronics.

A: THE EMITTER resistor sole function is to provide stability if it is by passed by a capacitor then this resistance will change due to frequency since as frequency increases the impedance decreases. The total gain will change accordingly

The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
To connect it to the circuit.
The function of a CVT is to provide a secondary voltage to equipment that is a direct ratio of a much higher primary voltage. They can also be used to couple communication signals onto transmission lines.
The primary function of a filter is to reduce the level of, or ideally eliminate, unwanted frequencies. There are three basic types of filter:Low pass which permits frequencies below a predetermined frequencyHigh pass the opposite of low passBand pass which permits a predetermined range of frequenciesNotch which permits everything except a predetermined range of frequenciesFilters can be analogue using resistor-capacitor or indutctor-capacitor networksor digital
The function that describes the current through a capacitor as a function of time is given by the equation I(t) C dV/dt, where I(t) is the current at time t, C is the capacitance of the capacitor, and dV/dt is the rate of change of voltage with respect to time.
The primary reason for a capacitor bank in an electrical substation is for power factor correction. There may also be some secondary purpose for the capacitor bank but the primary reason is power factor correction.
A fixed capacitor has a fixed capacitance (within certain limits influenced by aging). So it can fulfill any function that a (variable) capacitor fulfills, beside changing its capacitance easily (e. g. by turning a wheel).
In electronic circuits a capacitor is used to pass AC and block DC.
