The use of the micro- prefix for capacitance, i.e. microfarads, is common because the farad is a very large unit of capacitance and we don't normally use capacitors in that range of value.

What does micro farads measure?
A microfarad measures electrical capacitance. A farad can be defined as the charge in coulombs, which is 1 ampere per second, that a capacitor will accept for the potential across it to charge one volt. A microfarad is equal to one millionth of a farad.
Is a 45 5 Uf capacitor the same as a 45 5 mfd?
yes mfd is short for microfarad
Can you switch a 1800 microfarad with a 2200 microfarad capacitor?
A: I hope you mean replace. The answer is yes provided that the voltage rating is the same or more then the original.
What is the time constant of a .05 microfarad capacitor and a 200 kilo ohm resistor connected in series?
The time constant of a 0.05 microfarad capacitor and a 200 K ohm resistor in series is simply their product, 0.05 times 200,000, or 10,000 microseconds, or 10 milliseconds. (Farads times ohms = seconds)
Five capacitor replacement rules?
To replace a capacitoræyou must make sure that the replacement capacitors voltageæis equal or greater than the original, the microfarad (or strength rating)æis +/- 10 % of the original runæcapacitor, the microfarad of theæstart capacitor is +/- 20% of the original, for capacitors that are wired in parallell the microfarad must be equal to the sum of the individual capacitors, for capacitors that are wired in series the microfaradæis equal the reciprocal of the sum of the reciprocals of the individual capacitors.
If picofarad capacitor is replaced with microfarad capacitor then what will happend?
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.
Which value designates a 7-microfarad capacitor?
On the list that you posted with the question, there are no items that designate a 7 microfarad capacitor.
Can you replace 1.7 microFarad capacitor with 2 microFarad capacitor of capacitor start motor?
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
How do you repair a 680 microfarad capacitor?
To repair a 680 microfarad capacitor, buy a new one and install it in place of the old one. It is unrealistic to attempt repair of a capacitor.
Can a 47 microfarad capacitor in a microtimer circuit be replaced with a 470 microfarad capacitor?
No, the value is far too small. If it is the capacitor used for the timing, the time/s will be reduced to one tenth of the deisred value.
Which is heavier batteries or a capacitator?
What kind of question is this? If I have a button cell, then a 15000 microfarad 16v capacitor will obviously be heavier, and a 1 microfarad 50v capacitor will weigh less than an AA battery, which will be lighter than a high voltage supercapacitor.
What is the time constant of a 0.001 microfarad capacitor and a 15000 ohm resistor connected in series in a dc circuit?
The same as the time constant of a 2.7 microfarad capacitor and a 33 ohm resistor connected in series.
What is a 2200 capacitor?
I imagine 2200 is the value and usual is in microfarad a one farad will be a huge capacitor to be used in electronics.
What is the equivalent capacitance of 20-microfarad capacitor and a 50-microfarad capacitor that are connected in series?
It's the same formula as resistors in parallel: C = C1xC2/(C1+C2) C= 20 x 50 / 70 = 14.3 uF.
Can you change a 304 microfarad 370volts capacitor with a 305 microfarad 370 volts capacitor?
In most cases, yes. Unless you're in some high precision device, you're probably working with a 5-10% tolerance which would allow a 15-30 microfarad variance. Even a 1% tolerance would give you 3 microfarads. You can go with the same or higher voltage rating, just not lower.
In replacing the capacitor on a mig welder can i change a 53000 microfarad 30 volts capacitor with a 56000 microfarad 40 volts capacitor?
Yes you can do it. more voltage is good, a little more capacitance is good. Be sure to use a good quality capacitor. Note: on the old capacitor, it might be stated the temperature ratings such as 85 deg. C, 105 deg C, etc. Observe this as well. Higher is better.
