The farad (symbol: F) is the SI unit of capacitance. It is named after Michael Faraday. Definition A capacitor has a value of one farad when one coulomb of stored charge causes a potential difference of one volt across its terminals. Explanation Since the farad is a very large unit, values of capacitors are usually in range of microfarads (μF), nanofarads (nF), or picofarads (pF). The picofarad is comically called a "puff" in laboratory usage. The millifarad is rarely used in practice, so that a capacitance of 4.7�10−3 F, for example, is usually written as 4700 μF. Very small capacitance values, such as those used in integrated circuits may also be expressed in femtofarads, one femtofarad being equal to 1�10−15 F. A new technology called supercapacitors offers devices up to the kilofarad range. The farad should not be confused with the faraday, an old unit of charge nowadays superseded by the coulomb. The reciprocal of capacitance is called electrical elastance, the (non-standard, non-SI) unit of which is the daraf. A capacitor consists of two conducting surfaces, often referred to as plates, separated by an insulating layer usually referred to as a dielectric. The original capacitor was the Leyden Jar developed in the 18th century. It is the accumulation of charge on the plates that results in capacitance. Modern capacitors are constructed using a range or manufacturing techniques and materials to provide the extraordinary wide range of capacitance values used in practical electronics applications from femtofarads to farads and voltage withstand capabilities from a few volts to a several kV.

It you mean a cap then it's 1 farad for every 1000 watts. So you would want a 1.5 farad cap. Or a 2 farad would work as well.

Wiring 1 farad capacitor?

the capacitor has 2 wires or poles, one is the ground or negative and the other one is the hot or positive... if it is for car audio amp the ground is connected to the chassis and the positive is connected to the battery and to the positive wire of the amp.

On a run capacitor what does the MFD stand for?

Farad is the basic unit for capacitance. The MFD is an abbreviation for microfarad, which is one-millionth of a farad. The capacitance of a 50 MFD capacitor is one 50 millionth of a farad.

Would a 12 volt battery need to use a capacitor to run a 1000 or 760 watt amp?

I have a 760 watt amp powering 2 10" subs and it works fine. my brother has a 1000 watt amp powering 2 12" subs and he got a capacitor. So it really depends on what amp your looking at. if the 760w you wont need one, if the 1000w i would be safe and buy a capacitor. for the 1000w amp you would only need a 1 or 2 farad capacitor.

How many farads capacitor do you need for a 2000 watt amp?

It takes 1 farad for every 1000 watts so u need 2 farads.

Can an 2 farad capacitor still be used if the terminals were crossed at connection?

I Rather not think that you can buy 2 farad capacitor and no the terminals must follow polarity guidelines.

What would be the physical size of a 1 farad capacitor?

When used in car audio applications, a 1 farad capacitor is usually about 6" long and about 2.5-3" in diameter.

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.

Can you use a farad capacitor as a battery capacitor?

No. The large farad capacitors are not designed to pass a lot of current. They are intended for ultra-low current applications such as memory retention in a CMOS type device.

Does 001 farad of capacitor have polarity?

Only electrolytic capacitors (tantalum capacitors are a type of electrolytic capacitor) are polarized.0.001 farad = 1000 microfaradThis is a value that is too large for any practical capacitor except an electrolytic, so yes it will be polarized.

What if 10 micro farad capacitor is connected to 5 micro farad capacitor in parallel what would be the result?

Since the total capacitance for capacitors in parallel is the sum of the individual capacitances. I'm sure that you can work it out for yourself!
