    I am interested in what the voltage on the capacitor means. This means that the maximum voltage can be applied to it or it will be charged with a different voltage and it will generate a higher voltage. For example, I have a 100uF 35V capacitor. I will apply a voltage of 12V to it. I will take a meter and measure the voltage on the capacitor and it will be 35V or 12V?

    The 100u / 35V capacitor can connect max. 35V.
    And when there will be more ...

    And as for applying tension, how much you will have to apply.

    And if I pass 12V through it (that is, I will connect the current source to the capacitor and the bulb connected in series with each other).

    The voltage across the capacitor is its maximum operating voltage. If, for example, you charge the capacitor with 12V DC, the meter will show 12V. The capacitor does not generate any higher voltage.

    It is necessary to clearly distinguish the current voltage between the capacitor's facings and resulting from its capacity and the electric charge accumulated in it, from the nominal - allowable - operating voltage for this capacitor.

    It will charge up to the voltage to which you connect it, and the voltage on the housing means the maximum operating voltage, exceeding which may damage it. Regards.

    If it is a DC voltage source, the bulb will not light. At the moment of connection, a short current pulse will flow, which, depending on the power of the bulb, may cause it to flash. If you want to know why this is happening, read about capacitors, capacitive reactance and constant charging. Regards.

    I know because the capacitor is charging and then the bulb will not light up and when it is charged it gives its energy and then the bulb will flash and so on over and over again.

    Well, not really; P it is during the charging of the capacitor that a current flows, which can cause the light bulb connected to this capacitor to flash in series. When the capacitor is charged, this current drops to zero and nothing else happens. Regards.

Topic summary

The discussion centers on the voltage characteristics of a 100uF 35V capacitor. It clarifies that the maximum voltage rating (35V) indicates the highest voltage the capacitor can safely handle without risk of damage. When a voltage of 12V is applied, the capacitor will charge to that voltage, and a multimeter will read 12V across its terminals. The capacitor does not generate a higher voltage than what is applied. The conversation also touches on the behavior of the capacitor in a circuit with a bulb, explaining that the bulb may flash briefly when the capacitor is charging, but will not light continuously once the capacitor is fully charged, as the current flow ceases.
