Voltage Rating: If a capacitor cannot handle the voltage applied to it, it may fail prematurely. This is often due to selecting a capacitor with a voltage rating too close to the operating …
How do capacitors work?
Artwork: A dielectric increases the capacitance of a capacitor by reducing the electric field between its plates, so reducing the potential (voltage) of each plate. That means you can store more charge on the plates at the same voltage. The electric field in this capacitor runs from the positive plate on the left to the negative plate on the right.
