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.
with the help of function generator we found wave in oscilloscope
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
Bypass capacitors are used to bypass (shunt) unwanted signals to the ground. A common use is in power supplies where a bypass capacitor is connected in parallel with the main filter capacitor to shunt noise and other high frequency interference to ground which the main capacitor may not be able to do.
The function of a capacitor in a washing machine is to store a charge. This charge is what starts the washer.
The reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the capacitor

To connect it to the circuit.
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
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 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).

A capacitor is placed across the supply of a fluorescent lamp circuit to correct the power factor
