Yes, 100 MFD and 80 MFD capacitors will work in parallel, assuming they have the same voltage rating. The net capacitance will be 180 MFD.
That would depend on the tolerance of the capacitor. As the measured value is only about 2% below nominal and most capacitors have 10% or 20% tolerance it should be fine. However if it was a precision capacitor with for example 1% tolerance it would be bad.
The MFD (microfarads) or UF (microfarads) rating of a capacitor indicates its capacitance value, which measures the capacitor's ability to store electrical charge. One microfarad is equal to one-millionth of a farad, a standard unit of capacitance. Higher MFD or UF ratings signify a greater capacity to store charge, which can impact the performance of electrical circuits in applications like filtering, timing, and energy storage. Understanding this rating is crucial for selecting capacitors that meet the specific requirements of a circuit.
Capacitor values in certain applications can be very forgiving and in others quite critical. In power filtering for example you might be able to get away with the higher value. As long as the larger capacitor has the same or higher voltage rating you can give it a shot provided you understand that by doing so either it won't work or make harm your device.
Capacitor values can vary by 30% or so, but not double. The larger cap would draw too much current, possibly overheating.
The main difference is that lighting caps are required to contain a bleed resistor in parallel across the cap s terminals to drain the high voltage contained in the capacitor to safe levels (usually within a minute or so) after the equipment is switched off. Motor run caps don't require bleed resistors due to them being constantly connected to the motor windings which act like a resistor to drain the capacitor after use.
A: SURE capacitors in parallel will share the charge. But don't expect a .0001 mfd capacitor to charge a 1000 mfd capacitor. It just does not have the power stored to effectively charge the 1000 mfd. EXAMPLE 1litter of water cannot fill up a 5 litter container
It is a rating that is used to size capacitors in microfarad. MFD is an acronym for the word microfarad.
There are many different 'run' capacitors on motors. It depends on the motor make and use. You need to consult your manual or local electric motor shop.See related links below for good information on how capacitors effect motor starting.
Start capacitors and run capacitors are two different types of capacitors. They alter the current to create a rotating magnetic field. They have two or three terminals to which the wires are attached.
That would depend on the tolerance of the capacitor. As the measured value is only about 2% below nominal and most capacitors have 10% or 20% tolerance it should be fine. However if it was a precision capacitor with for example 1% tolerance it would be bad.
Yes, we can replace it
Sometimes. The exception is when the capacitor is used as a "timing" device. But 7.5 mfd and 5 mfd are so large that one would guess that they are not being used as timing devices.

It's a long-obsolete symbol for microfarad. It also appears capitalised, MFD.

yes mfd is short for microfarad
It could simply be a newer design, but it is also possible that the RMS current rating is different. Check the requirements against the data sheets.
