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 fixed capacitor used in electronic equipment.
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
A capacitor is placed across the supply of a fluorescent lamp circuit to correct the power factor
Function of Capacitor in Air Conditioner:Compressor Motor Capacitor: This air conditioning capacitor usually consists of two capacitors that are combined. This vital capacitor gets the motor running in the air conditioning unit.Start Capacitor: This capacitor provides auxiliary support and that is not a standard on every air conditioning unit. It can give the motor a boost to get it started.Indoor Blower Motor Capacitor: This capacitor is self-explanatory. It is responsible for starting the indoor-blower-motor and keeping it running efficiently.Outdoor Fan Motor Capacitor: The name says it all for this capacitor. It starts the outdoor fan and keeps the air flowing through the coils that run on the outside of an air conditioner.
Most fixed capacitors, and almost all variable ones, have no polarity. That is, itmakes no difference to the capacitor which side you make positive and which sideyou make negative, and your choice has no impact on the performance or lifetimeof the capacitor.Electrolytic capacitors and some tantalum ones do have a preference, and thepolarity of their two leads is marked on the component. Their dielectric is formedby an internal electro-chemical process that depends on the polarity, such thatthe dielectric goes away if the polarity is reversed, and then you no longer havea capacitor.
Yes you can. But the variable one is used so that you can very the frequency and it cant be varied anymore if you use a fixed capacitor.
A capacitor having a definite capacitance value that cannot be adjusted. Viper1

Sure brah

variable capacitors are those capacitors which can be intially or randomly canged by the user for example radio tunning.whereas fixed capacitors are those whose value is fixed and can't be changed. sohaib
the capacitor and its associated resistor set the time constant.

To connect it to the circuit.
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 symbol for a fixed capacitor in electronic schematics is typically represented as two parallel lines, with one line slightly longer than the other. This symbol indicates the two conductive plates of the capacitor. Depending on the specific type of capacitor, additional markings or labels may be included to denote its capacitance value or voltage rating.
Gang capacitors are commonly used in radio tuners/receivers. Radio tuners/receivers have formation of LC(inductance and capacitor). Here this circuit has one fixed inductance and capacitor parallel with gang capacitor. Normally gang capacitor used in superhetrodyne receiver.
