A capacitor is designed to store energy over time and then release it nearly instantaneously. If you are holding it by its leads it could discharge and kill you.

What is held by power supply capacitor?
Capacitor store electrostatic energy in form of electric field.
How do you determine capacitor's condition using multimeter for small capacitance?
You can use a multimeter to check the condition of a capacitor by using its highest range for measuring resistance. That range applies the highest voltage - often 9 volts - to the capacitor.If the capacitor is of a polarized type - such as electrolytic - you must be sure to apply the multimeter's test leads to it the correct way round so as to apply the voltage in the right direction so that the capacitor can charge-up.If the capacitor is shorted internally the multimeter will always show a low resistance.If the capacitor is not shorted internally and is in good condition you will see a low resistance at first but, as it charges-up from the applied voltage, you should see the resistance rise in a steady manner until it registers near to infinity.If the capacitor is failing the resistance will stay fairly low because the charge will not be held. If the capacitor is in good condition the charge should be held for several hours and the capacitor can be discharged (by shorting its wires) and then recharged repeatedly.Warning Never ever try to test a capacitor whilst it is still connected into a circuit because: * it must always be discharged safely before you try to test it because you could receive a bad electrical shock if the capacitor is still holding a charge from being in-circuit. Wear rubber gloves on both hands and short its leads away from your eyes because, if it was holding a high voltage charge, there may be a big spark!* other circuit components may get damaged, especially if they are semiconductors;* other circuit components may prevent the capacitor from being charged-up.
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.
If a 0.40-uF capacitor is connected to a 9.0-V battery how much charge is on each plate of the capacitor?
The units of capacitance are called farads. A one farad capacitor is a capacitor with 1 volt potential difference with 1 coulomb of charge on the capacitor, C = Q/V or Q=CV So the charge held on your capacitor is Q = CV = 9Volts * 0.40*10-6Farads=3.6*10-6 Coulombs

Placed its proper casing after thorough cleaning.
Is a zoo somewhere for animals to be all the time?
Yes animals should be held captive forever and ever. They should never be let out
How close should a one year old be held to a fire even?
A one year old should never be held to a fire. That would constitute child abuse (not to mention the danger of setting him aflame!)
