Capacitance of capacitor

  1. Nov 5, 2015 #1
    suppose i have a circuit,in which a capacitor and resistances are connected in series with a DC voltage source.
    then after a long interval of time we know that capacitor will have same voltage across its terminal as that of DC voltage source and no current flow in the circuit.
    so, can i say at that time, my capacitor is fully charged.....

    Yes, fully charged at that voltage. If you raise the DC voltage, the capacitor can store more charge.

    that means capacitance of a capacitor is increases with increase in DC voltage around it !

    i think this is not true........

    No. The charge stored increases, not the capacitance. Capacitance C is defined as the ratio of charge Q to voltage V. C=Q/V

    ok...i got it...

    thanks a lot......
