Not sure what you mean by an AC capacitor. They store a DC voltage or pass an AC signal.
If it is a large capacitor used in mains power supplies, it is best to discharge it before working on it, to avoid an electric shock.
In this case it is best to discharge it using a resistor of about 100k.
If you cause a dead short, the large current can either burn you, or cause the capacitor to explode.!

What will happen if you changes the polarity of the capacitor in their respective position?
It will either explode right away, or work for a short time then explode. Note though, that the capacitor's polarity only applies to DC voltage. Because AC flows through a capacitor, if there is no DC offset, it matters not which way the capacitor goes.
Is a 45 5 Uf capacitor the same as a 45 5 mfd?
yes mfd is short for microfarad
Can you by-pass a capacitor in an electric motor?
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.
Why to short circuit capacitor in small signal analysis of BJT?
if the input signal passes through the biasing resistors, the biasing conditions get altered . To prevent this, the input signal should be directly sent to the amplifier (BJT) .Since a capacitor acts as a short circuit for ac signals,capacitors are placed both in the input side and the output side.
What is the purpose of a blocking capacitor?
At high frequency, capacitor can be considered as 1. Short Circuit in AC analysis. 2. Open Circuit in DC analysis. {because Xc= 1/(2*f*pi) where f= supply frequency,pi=3.14} As at high frequencies, in DC analysis, capacitor will be open circuited & can block the DC signal while AC signal is allowed to pass through.. Hence, this capacitor will act as a blocking capacitor for DC supply.
