Sparking between contacts can be reduced by inserting a resistance?
Capacitor in parallel with contacts.
What effect will be produced on a capacitor of the separation between the plates is increased?
Nothing until the potential difference produces an electric field stronger than the insulation in the capacitor can take. Then it will spark over. For an air capacitor that is approximately 33,000 volts per centimetre in dry air, so for spacing of 0.25 mm the sparking voltage would be around 700-800 volts
How do you reduce elctrical harmonics?
You will need to calculate a capacitor at the output stage in order to prevent interaction with the networks connected after the output.
What is function of snubber circuit?
capable of resetting the transformer as well as eliminating leakage inductance voltage spike across the switch
What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .

What is the advantage of capacitor filter over inductor filter?
An inductive filter is in fact an LC circuit in which an inductor is connected in series with the capacitor. This arrangement is also known as a low-pass filter. http://www.answers.com/topic/inductive-filter
What type of capacitor should be charged slowly after not being used for a period to prevent damage if a sudden surge?
if exact replacement capacitors are not available,you should substitute it with a capacitor that has

How do you change a bad capacitor in an air conditioner?
Locate the defective capacitor, short the terminals to ground to release any stored energy and prevent shock, remove the old capacitor then install the new capacitor wired as the old one was and secure it in the bracket that held the old one - done.
How do you prevent shock by capacitors?
Discharge the capacitor, normally with a resistor accross the terminals (Calculated size)
Is Sparking between contacts can be reduced by inserting a Resistance in the line?
not it will be more effective to use a capacitor in parallel...1/WC->0 as high frequency switching waves w-> inf.C provides a shrt circuit path.

What two facctors determine the capacitive reactance of a capacitor?
The reactance of a capacitor is a function of -- the capacitance of the capacitor -- the frequency of the voltage across the capacitor
