Why capacitor in transistor amplifier circuit at input?
Because capacitor not allow to pass dc voltage,but capacitor allow ac voltage and signal.Purpose is to block dc voltage.That is coupling condenser.
What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?
The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
Regarding Capacitors- can any general capacitor work on a circuit diagram that shows a polarized capacitor or do you need a special capacitor for polarization?
A Polarized capacitor means that the capacitor is polarity sensitive. if you were to connect the capacitor incorrectly the capacitor would blow up. A capacitor that is marked as being polarity sensitive will have the negative lead labeled usually with a white strip. These capacitors can only be used in conjunction with a dc source. Always consult a professional when installing electrical equipment.
What happen to the energy stored in the capacitor while the capacitor is discharging?
It flows out of the capacitor into the external circuit
How one can know that what kind of capacitor to use in circuit?
paper capacitor
Can Homework cause a student to fail?
If you don't do your homework -- yes, it will cause you to fail. Doing homework will not cause you to fail.
What is the purpose of capacitor in power supply higher than rated voltage?
The voltage marked on a capacitor is its MAXIMUM SAFE WORKING VOLTAGE. The capacitor will work in a circuit at any voltage lower than that, but it may fail at any higher voltage.
Why in the experiment of flashing and quenching of capacitor the neon bulb start twinkling?
In the experiment of flashing and quenching of a capacitor, the neon bulb twinkles because the charging and discharging of the capacitor cause the voltage across the capacitor to fluctuate rapidly. These fluctuations can cause the neon bulb to turn on and off, leading to the twinkling effect.
What will happen if negative sequence relay is absent in generator?
The flux capacitor will overload and you will fail to reach 88 mph.
Why do connections attempts from other networks fail even though they are not specifically listed in the ACL?
Because the flux capacitor is broken.
Does a 2 farad capacitor cause surging and lights to flicker?
The capacitor will not cause dimming, whatever it is that the capacitor is being used for (usually helping drive a bass amp) is what causes the dimming. A capacitor is a quick charge and quick discharge battery basically, so when the amp has depleted the power in the cap it still must go to the car battery for power and that is when there will be dimming lights.
Cause of single phase capacitor start motor burning?
mainly due to undervoltage.
Will amoxicillin cause you to fail a drug test?
No.
Will Orexis cause you to fail a drug test?
No
Will orajel cause you to fail a drug test?
No
Handling marijuana cause UA fail?
No.
When might it be necessary to use a 2 µF polyester capacitor rather than a 2 µF electrolytic capacitor?
when high voltages are present because the voltage rating of polyester (polyethylene terephthalate) capacitor is high as well as electrolytic capacitor will destroy if the voltage increases from nominal voltage and cause short circuit conditions.
