Does the physical size of a capacitor make a difference if the values are correct?
The only criteria governing capacitor size is; will it fit into the space on the circuit board.Capacitors produce a reactance that is measured in ohms - depending on the alternating frequency of the current flowing through them - and that reactance will produce heat.So, if you are designing equipment that will use a capacitor - or are replacing a defective capacitor - you must take into account how much energy it will produce as heat, that will have to be conducted away, otherwise the capacitor will burn up! So you must never use a capacitor that is physically too small for the job!The answer given above needs is partially correct in that it should also say that, as long as it will fit into the space available, you can use a capacitor of the same microfarad value that is physically bigger than the one that you are replacing but you should never use one that is physically smaller.It is also important to use the correct type of capacitor: it may not be safe to replace a non-electrolytic type by an electrolytic one, for instance.Not all capacitors are used in printed circuit boards. A capacitor used for motor starting also has to be matched exactly when replacing, as it also is engineer designed to the characteristics of the motor.
Can an 2 farad capacitor still be used if the terminals were crossed at connection?
I Rather not think that you can buy 2 farad capacitor and no the terminals must follow polarity guidelines.
Can you change a 440 volt 12.5 uF start capacitor with a 370 volt 12.5uF run capacitor?
There are two ways to read this: you have a burned-out run capacitor on your motor and a good start capacitor in your parts box, and you have a burned-out start capacitor and a good run capacitor. If the run capacitor's bad and you want to put the higher-voltage start cap in its place, the answer is yes. This is called derating, and the only thing it does for you is increases the lifespan of the capacitor because you're not working it as hard as it can take. If the start capacitor's bad, don't do this--they used a 440-volt capacitor in there for a reason.
How do you differentiate a start capacitor from a run capacitor in air conditioner?
If the air conditioner has both, the run capacitor is likely the largest one. The start capacitor will only be in the circuit for a very short time, so overheating doesn't become an issue. The run capacitor must be sized for continual use.

Do all motors that use capacitors must have at least one run capacitor or a run and start capacitor true or false?
true
How do you increase the value of a capacitor?
A: Any additional capacitor added in parallel will effectively increase to total capacitance by that value. Note that additional capacitor added must have the same voltage rating as the other
