A: As soon as a DC voltage is applied the capacitor is a short or no voltage
The voltage marked on a capacitor is its MAXIMUM SAFE WORKING VOLTAGE. The capacitor will work in a circuit at any voltage lower than that, but it may fail at any higher voltage.
Yes, it will work fine. The downside is that it might cost more than one of the lower voltage rating, or that it might be physically larger. A capacitor voltage rating is a maximum, so any lower voltage is also acceptable.
The voltage rating of a capacitor tells the user how much voltage the capacitor can withstand. If a user exceeds this voltage, the capacitor's dielectric may be damaged and destroyed.
yes a capacitor can improve voltage by improving power factor
AC can pass through a capacitor. The higher the frequency of AC the lower the reactance (like resistance). The current and applied voltage are 90 degrees out of phase the current leading the voltage by this amount.
No, the voltage across a capacitor cannot change instantaneously. It takes time for the voltage across a capacitor to change due to the storage and release of electrical energy in the capacitor.
For part of the AC voltage wave, the capacitor will be above the source voltage, and will discharge until the AC voltage wave increases above the capacitor's stored voltage.
A capacitor discharges by releasing stored electrical energy. The rate of discharge is affected by factors such as the capacitance of the capacitor, the resistance of the circuit, and the voltage across the capacitor. A higher capacitance or lower resistance will result in a slower discharge rate, while a higher voltage will lead to a faster discharge.
you cannot increase the voltage by replacing a capacitor. A capacitor is a passive components it has no gain.
Yes. You just don't want to exceed the voltage rating of the capacitor.
the voltage number on the capacitor indicates that the capacitor can with stand to that particular voltage across it.generally during design, the value of capacitor will be selected in such a way that this voltage rating should be double than what really we get in the circuit
