What Does The Information On The Side Of A Capacitor Mean? For example: 80uf 200v

[NNNOOOOOO 0]

Is it the capacitance and max voltage, or capacitance and voltage no matter what the power supply voltage. Lets say the voltage on the side is 50v. If I connect a 9v battery to it, will the capacitor hold only 9v because that's what i'm giving it, or will it charge all the way to 50v?

The voltage marking is the maximum working voltage for the capacitor. Above that voltage the capacitor will break down or even explode. After charging, the capacitor will decay from that voltage downwards (if it had a higher voltage, energy would have been created, which is impossible).

Thank you. I wanted to know that before putting one in an electrical circuit.
