An air variable capacitor might have a range of a few picofarads (high voltage units) to several hundred picofarads (in an old AM radio).
A capacitor whose capacitance is variable (within some range). They are usually used to adjust resonant circuits or delay circuits.
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.
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
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.
A trimmer capacitor is a semi-adjustable capacitor placed across a variable tuning capacitor and pre-set to allow the main capacitor to track correctly with another variable capacitor on the same shaft. The adjustment takes out any differences introduced by the connected circuit.
That depends on the value of the capacitor and other components in the circuit.

A variable capacitor is an electronic subcomponent that allows the user to tune the device to various capacitances within its range. For example, an air-dielectric variable capacitor with a range of between 5pF and 100pF could be tuned by rotating its shaft, and would contribute anywhere between 5pF and 100pF of capacitance depending upon the angle of the shaft.

A capacitor microphone, also known as a condenser microphone, uses a capacitor to convert sound waves into an electrical signal. It is known for its sensitivity, wide frequency range, and ability to capture subtle details in audio recordings. These microphones are commonly used in studios for recording vocals and acoustic instruments.
