What is the difference between capacitor and capacitance?
A capacitor is a device that stores an electrical charge, or if you prefer- resists any change in voltage applied to it. Capacitance is a measure of the size or ability of a capacitor to do that. This is the Farad
What size capacitor is in a taser?
It is usually 80-100 UF(micro farad)
What does the farad rating mean in capacitors?
The rating or 'size' of a capacitor, called its "capacitance", is related the amount of charge the capacitor can store, to the amount of energy it holds when it stores some charge, and to the opposition of the capacitor to the apparent flow of alternating current through it. If a capacitor has a capacitance of 1 farad, then -- One coulomb of charge stripped off of one plate and added to the other plate produces 1 volt of potential difference between the plates. -- The energy stored in the capacitor is 1/2 the square of the voltage across it. -- Its impedance is (0.159 divided by the frequency) ohms. The farad is an enormous capacitance. A typical capacitor used in a 'lumped' circuit ... the kind of construction where you would buy a capacitor and solder it in ... has a capacitance in the range of maybe 10 picofarads (trillionths of a farad) to maybe 100 microfarads (millionths of a farad).
Why should you discharge the capacitor before measuring the capacitance?
If you don't it could fry your equipment. A capacitor can hold a charge for anextremely long time even years depending on the physical size and capacitance. It can hold a strong enough charge to kill.
What size capacitor does ducane condensor AC10B48-A?
89M77 40+5MFD-440VAC dual run capacitor
What size capacitor you need for a 1000 watts amplifier?
It takes 1 farad for every 1000 watts so u need 2 farads.

What is the SI unit of a capacitor?
Capacitors are measured in Farads or microfarads.
What do you measure capacitors in?
Capacitors are characterized by two values: their voltage, exceeding which will damage the capacitor (sometimes leading to a violent explosion), and their capacitance, as the name suggests. The voltage is expressed in volts. The capacitance is expressed in Farads. One (1) Farad is an amount of charge that makes the voltage across the capacitor terminals to rise by 1 Volt. If a 10mA current flows into the capacitor and it causes the capacitor's voltage to rise by 1V every second, the capacitor's capacitance is 10 milifarads. 1 Farad is a lot of charge, so for most applications, submultiples (microfarads and milifarads, mostly) are commonly used. A curious note: the more voltage a capacitor can handle, the (usually) bigger the size of it. At low voltages and low capacitance, the capacitance doesn't influence the size that much, though.
What size capacitor do you need for a 3000 watt amp?
u should be good w a 3 Farad Cap, but did u do an apgrade called "Big3" and then, i might wanna get a bigger alternator, and a 2nd/new battery
Is it OK to use an unpolarised capacitor in a circuit where there was originally a polarised one?
Well... Maybe yes, maybe no. It depends on two things. First, the physical size of the non-polarized capacitor may well be larger than the original size of the polarized capacitor, so it might not fit. Second, you have to consider the RMS current rating of the capacitor. Often, a polarized capacitor, such as an electrolytic capacitor, is intended to be used in a power supply, and is rated for a certain RMS current. A non-polarized capacitor, however, might not be rated for the same or higher RMS current, so it would not be able to handle the load.
How do i size up a start capacitor?
Read the capacitor that you remove

If you don't it could fry your equipment. A capacitor can hold a charge for anextremely long time even years depending on the physical size and capacitance. It can hold a strong enough charge to kill.
What is capacitance measured in?
. . is measured in farads or more usually microfarads or even picofarads. A capacitor has a capacitance of 1 farad when it has a voltage of 1 volt when there is 1 coulomb of charge on each plate. 1 coulomb is 1 amp flowing for 1 second.
What size capacitor?
Capacitors come in various sizes, your question is to non specific (capacitor for WHAT) for a detailed answer.
