By connecting the two leads together.
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.
Will a capacitor lower voltage?
A: As soon as a DC voltage is applied the capacitor is a short or no voltage
Why is rectified voltage storge in a capacitor?
Because a capacitor is ideal for storing energy over short periods, as in a reservoir capacitor in a power supply.
What stores fast short -term energy?
A capacitor.
What happened when capacitor is infinite?
it works as a short ckt
Effect of shorting out the capacitor in a clamping circuit?
Any circuit using a capacitor will not work if the cap is short-circuited.
What dies a capacitor do?
Either the electrolyte leaks out or it develops a short across the plates.
How capacitor behave in alternating current?
Capacitors have an equivalent reactance of 1/jwC (ohms) where w is the angular frequency of the AC signal and C is the capacitance. As the frequency of the signal across the capacitor increases, the capacitor reactance approaches 0 (capacitor acts like a short circuit). As the frequency of the signal across the capacitor decreases, the capacitor reactance approaches infinity (capacitor acts like an open circuit). So, if you have a high frequency signal (like a step input) the capacitor will momentarily act like a short.
What is the name of the component that stores electricity for a short period of time?
capacitor
When DC power is first applied to an uncharged capacitor it appears as a?
When DC power is first applied to an uncharged capacitor it appears as a short circuit.
What is the meaning of a capacitor been shorten?
A shorted capacitor is one where the gap between the plates is damaged, and the plates are touching each other, creating a short circuit.
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.
What is the function of a bypass capacitor in an amplifier?
Bypass capacitors are used to bypass (shunt) unwanted signals to the ground. A common use is in power supplies where a bypass capacitor is connected in parallel with the main filter capacitor to shunt noise and other high frequency interference to ground which the main capacitor may not be able to do.
