Which type of a capacitor is used for power factor correction?
A.C capacitorAnswerGenerally speaking power-factor capacitors are oil-impregnated paper capacitors -i.e. capacitors whose dielectric is manufactured from oil-impregnated paper. Power-factor capacitors are rated in reactive volt amperes, rather than in farads.There is no such thing as an 'AC capacitor', as all capacitors (other than polarised capacitor) can operate on either AC or DC.
Why should you never operate a flash that has just been drenched in water?
The energy stored in an electronic flash unit may well be lethal. Capacitors can store large quantities of energy, and at high voltages. When working on equipment with large capacitors you should discharge them safely, and again, and again. For a capacitor will not release all its energy in the first discharge cycle. Flash units contain such capacitors.
Are capacitors polarity sensitive?
The capacitors those are polarity sensitive are called electrolytic and tantalum capacitors. These capacitors are labeled as positive and negative.
How are capacitors rated?
Capacitors are rated in Microfarads
What is the difference between electrolytic capacitors and normal capacitors?
because normal capacitors does not have any polaririties.
Why you use capacitor in ic7805?
The manufacturer's data sheet actually recommends using two capacitors with any 3-terminal regulator in the 78xx family: a 0.33µF on the input and a 0.1µF on the output.the input capacitor functions mostly as a filter capacitorthe output capacitor functions mostly as a decoupling capacitorHowever both capacitors should be ceramic capacitors (to reduce parasitic inductance in the capacitors) so that they can operate efficiently at the high frequencies resulting from rapid circuit switching in the load (especially if the load consists of digital logic).
Whether film capacitors can be replaced with ceramic or mica capacitor?
Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. However, mica capacitors can be replaced with ceramic capacitors in general.
How can you stop Television from humming?
Replaced capacitors that are no lomger capacitors.
What is the population of Nokian Capacitors?
Nokian Capacitors's population is 290.
When was Nokian Capacitors created?
Nokian Capacitors was created in 1957.
Why do capacitors leak?
Mostly the leakage of capacitors is due to the resistor.
Why Bypass capacitors used in electronic amplifier?
A: A transistor needs a bias or voltage to operate in a linear region unfortunately that is detrimental to gain so by bypassing this emitter voltage the AC gain can be improved.
