One farad is equal to?
Farad is a unit of capacitance - to measure the capacity of devices called capacitors. Farad means coloumb/voltage, in other words, if the capacitor has a capacity of 1 farad, it will store a charge of 1 coloumb for every volt. This is a huge unit; real capacitors are usually specified in microfarad, nanofarad or picofarad.
farad is the unit for capacitance in SI system. If one volt is developed as one coulomb charge is placed then capacitance has to be one farad. But one farad is enormous large one so practically speaking we use only micro farad, nano farad and pico farad. They are respectively 10-6 F, 10-9 F and 10-12 F
A Farad is the electrical unit of capacitance. Many commonly used capacitors (also known as condensors) are measured in micro-Farads (μF). A micro-Farad is one millionth of a Farad. To convert from micro-Farads to Farads, divide the micro-Farad value by one million. 2 micro-farads = 0.000002 Farads.
I'm not sure where you are getting your information. Capacitors come in a large range - nano farad to several farad. The higher the farads, the bigger (in general) the capacitor will be. For example, amazon has a 1 F, 20 volt cap for ~76.00. I would consider this to be "generally available in the market". If you want a 1 farad cap for 120 volts, it's going to be substantially bigger than this one…
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…
The unit of capacitor is farad. 1 farad =10 to the power of 6 microfarad and also = 10 to the power of 12 picofarad Therfore if you are replacing one picofarad capcitor into one microfarad capacitor you are increasing the capcitance to 1000000 times. If it is in an oscillator circuit you are changing the frequency drastically which will be of no use.
