It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
The same as the time constant of a 2.7 microfarad capacitor and a 33 ohm resistor connected in series.
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.
It's the same formula as resistors in parallel: C = C1xC2/(C1+C2) C= 20 x 50 / 70 = 14.3 uF.
100 microfarad
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.
30 microfarads
It is a rating that is used to size capacitors in microfarad. MFD is an acronym for the word microfarad.
On the list that you posted with the question, there are no items that designate a 7 microfarad capacitor.
1000
1K = 1uF
Type alt + 230
1000000 microfarad
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.
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
uF is a measurment in electronics called Microfarad. You will typically see uF on Capacitors for example 400Volt 150uf would be a capacitor rated at 400 volts and 150 microfarad.
A: I hope you mean replace. The answer is yes provided that the voltage rating is the same or more then the original.
