The run capacitor is used when the load is functional while the start capacitor is used to produce the initial torque to drive the load.
Read the capacitor that you remove
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.
Electrolytic capacitors look like little batteries. Any capacitor that looks like this will be electrolytic.Another AnswerElectrolytic capacitors are polarised, so their terminals are marked with positive and negative symbols.
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.
The run winding of a single phase capacitor start motor has a lower resistance than the start winding.
No

A start capacitor is wired in series with the motor's start winding via a centrifugal start switch. The switch disconnects the capacitor and start winding once the motor has reached a pre-determined minimum speed. The motor then continues to run on its main field winding. A different design uses a "start-and-run" capacitor which remains in circuit whilst the motor is running.

No. You won't be able to start the motor without the capacitor.
If you mean run capacitor, as in the run capacitor for an AC motor, it is usually a round or oval cylinder.
