The capacitor on it's own is of no use, it is always used in an RC or LC configuration normally in audio frequency's the RC is used to filter the noise down to earth where the RC circuit have to resonate at the same frequency as the noise, the lower the frequency the larger the value of the capacitor
What else can I help you with?
Why bypass capacitor of the second stage to disconnect to get the output?
we can use the Out Put Capacitor Ex Kvar
Why use capacitor in circuit?
To smooth the output of the pulsating DC.
What is effect of noise on digital communication system?
it will affect the output of a receiver only if it falls within the passband.in that case,the carrier and noise voltage will mix and the difference frequency,if audible,will interfere with the reception of the wanted signal..
How do you reduce elctrical harmonics?
You will need to calculate a capacitor at the output stage in order to prevent interaction with the networks connected after the output.
What is the function of a bypass capacitor in an amplifier?
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.
What is the effect of the filter capacitor on the output wave shape of the rectifier?
The larger the cap the smaller the ripple at the power supplies output. It smooths the rectifiers output waveform.
DC blocking in a transistor is achieved by?
Including a series capacitor in the input and/or output circuit of the transistor. If the capacitor in the output circuit is omitted there will be a dc component in the output.
Why bypass capacitor of the second stage to disconnect to get the output?
we can use the Out Put Capacitor Ex Kvar
What is the effect of a leaky capacitor filter on the output of a full-wave bridge rectifier?
A: The leakage is an additional load to the bridge effect is that the capacitor will get hot then hotter because of it leaks more eventually blows hopefully open or dead short. both of these scenario may save the power supply.
How do you determine the size of acapacitor in a rectifier circuit?
ANSWER In rectifiers for power supplies, the capacitor size is determined by the allowable ripple on the output. This can be determined by the rate at which the capacitor is drained. Specifically, this rate is the current drawn from the capacitor. Assume a half wave rectifier made from four diodes. For part of the cycle, the output current is supplied by the rectifier diode. This is also when the capacitor is charged. While the rectifier is not supplying current -- when the input waveform has dropped below the output voltage -- the capacitor must supply the current. Then, as the input waveform rises above the capacitor voltage, the rectifier supplies the current to charge the capacitor and the output circuit.
Why use the capacitor in the full rectifier?
to smooth the output waveform
Why use capacitor in circuit?
To smooth the output of the pulsating DC.
If vm is maximum peak voltage of rectifier outputthis rectifier output is connected to the capacitor filterwhat will be the approximate dc output voltage to the capacitor filter?
It should be the rms value of your supply.
What is the effect of the magnetic field between capacitor plates on the overall performance of the capacitor?
The magnetic field between capacitor plates does not have a significant effect on the overall performance of the capacitor. The main factors that affect a capacitor's performance are its capacitance, voltage rating, and dielectric material.
Why does a heater blower have a humming noise when the motor is running?
If the heater blower has humming noise when motor is running, first check its capacitor. If the capacitor is fine, then the motor is the problem and may need to be replaced.
Why capacitor used in rectifier circuit?
To smooth the output of the pulsating DC.
