Things that are fard are things that you have to do ( obligatory) and sunnah is the actions the prophet Muhammad did and its your choice whether to do it or not
about 500 uF
Theæ definition of farad is as follows; SI unit of capacitance, formally defined to be the capacitance of a capacitor between the plates of whichæthere appears a potential difference of one volt when it is charged by a quantity of electricity equal to one coulomb.
Farad
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
I read that it 500 rms to 1 Farad.
One farad is equal to one coulomb of electric charge stored per volt of potential difference across a capacitor. In simpler terms, a capacitor has a capacitance of one farad when it can store one coulomb of charge for every volt applied across it. This unit is named after the physicist Michael Faraday.
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.
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).
A farad is not equivalent to a volt or an ampere, as these units measure different electrical properties. Specifically, a farad is the unit of capacitance, representing the ability of a component to store electrical charge per volt. In contrast, volts measure electrical potential difference, while amperes measure electric current. Therefore, while they are all part of the same electrical context, they represent distinct concepts.
The SI unit of capacitance is the farad. 1 farad is 1 coulomb per volt.
The Farad is a measure of how much electric charge is accumulated on the capacitor. Named after Michael Faraday
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.
