It will minimize curent flutuations, it olso helps in AC circuits( in AC I tink it absorbs frequenci emmisions).

Can we use AC capacitor in surge suppression circuit DC?
A capacitor is a capacitor, no matter what circuits you use it in. There is no difference between one used in AC and one in DC, except perhaps the size that is appropriate.
Why capacitor is used in between the bias circuit?
Capacitor is used in biasing circuits to block the passage of DC signals.
What is the function of mylar capacitor?
In electronic circuits a capacitor is used to pass AC and block DC.
What is the purpose of a blocking capacitor?
At high frequency, capacitor can be considered as 1. Short Circuit in AC analysis. 2. Open Circuit in DC analysis. {because Xc= 1/(2*f*pi) where f= supply frequency,pi=3.14} As at high frequencies, in DC analysis, capacitor will be open circuited & can block the DC signal while AC signal is allowed to pass through.. Hence, this capacitor will act as a blocking capacitor for DC supply.
Why does Jim use dc supply in oscillator circuits?
Jim use dc supply in oscillator circuits to and ac out put.
What is the labeling nomenclature for capacitors and how is it used to identify and select capacitors?
Capacitors are marked with the capacitance and the maximum working voltage. The action of a capacitor is store charge short-term and a capacitor is commonly used as a reservoir of charge in a rectifier circuit to smooth the dc output voltage. Other uses in electronic circuits are as a dc-blocker which passes an ac signal while not passing the dc bias, or as a decoupling capacitor in dc circuits to remove any ac signals present while preserving the dc voltage, or in timing circuits because the time-constant of a resistor and a capacitor connected together is CR, or in filters and tuned circuits. Sometimes a variable capacitor is used, connected to a control knob for tuning a radio. In each of the above applications there are accurate methods to decide exactly how much capacitance is required.
Is paper capacitor use in transistor amplifier?
It can be, but may not be required. Capacitors are used for biasing purposes, to remove DC from inputs, and for filtering in amplifier circuits (just to name a few).
Why coupling capacitor is used inelectronics circuits?
To Block DC voltages and couple AC signals through to the next circuit.
What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
Why use capacitor in circuit?
To smooth the output of the pulsating DC.
Can a capacitor be hooked to a DC circuit?
Yes, capacitors can be, and often are, used in DC circuits. At steady state DC conditions, the capacitor has near infinite impedance. Its value is in its ability to resist changes in voltage, so it can serve as a transient filter. There is almost always a small ceramic capacitor connected between VCC and ground next to IC's in a digital circuit, for that exact purpose.
Where you have requirement of capacitor in electronics?
A capacitor is required in electronics when we are charging and frequency circuits.
