Sure brah
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 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 having a definite capacitance value that cannot be adjusted. Viper1
A fixed capacitor used in electronic equipment.
They can physically be located almost anywhere. Capacitor banks are typically attached to the bus in substations. Reactors are often tapped off lines.
Yes, but not for ever. A capacitor can never be perfectly insulated and it has a small leakage current, that causes it to discharge eventually.
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
Capacitor banks can improve the power factor if the load is leading, which is unusual. Typically in substations capacitor banks are employed to reduce over voltage.
Series reactors may be used in switching in capacitor banks. These are used to minimize the transient voltage spikes on the system resulting from switching in a capacitor bank.
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.
No, capacitor banks reduce harmonics. They act like a low pass filter. They also raise voltage by compensating for inductance and bringing the power factor back closer to 1. Capacitor banks in the power system can cause transients when randomly closed - many utilities use zero voltage closing equipment, or inductors to counteract this short time harmonic problem.
A fixed order quantity system is the arrangement in which the inventory level is continuously
