    according to this when the capacitor is fully charged the current in the circuit is zero

    eduncle-logo-app

    is it correct

    eduncle-logo-app

    it's like that.....when capacitor is fully charged it accommodate maximum charge and we will remove the voltage source from here bcoz we don't neee it now. and capacitor will start discharging.

    eduncle-logo-app

    so during discharging the current flow.will be equal to what you have derived do you want to say this

    eduncle-logo-app

    means when we removw the voltage source then capacitor behaves as voltage source

    eduncle-logo-app

    am i right

    eduncle-logo-app

    exactly....basically current means what....rate of flow of charges...... so it would be same in both situation

    eduncle-logo-app

    the rate at which charge accommodate will be same as charge decreasing.

    i am accepting your answers. just i was clearing my doubts and hey are cleared noe

    eduncle-logo-app

    thanks

    eduncle-logo-app

    dear just clear your whole doubts..... it's really good.

    eduncle-logo-app

    m here for helping you

    eduncle-logo-app

    ok

    eduncle-logo-app

    most welcome dear.......plz ask ur doubts if u have.

    eduncle-logo-app

    no they are cleared

    eduncle-logo-app

    happy to help u dear

    can you provide the derivation of the first equation you have used

    eduncle-logo-app

    yes dear......i hv attached plz see that

    eduncle-logo-app

    what do you mean by current flow by charging capacitor

    eduncle-logo-app

    when we are adding voltage source first chage will accommodate in capacitor

    eduncle-logo-app

    yes then after that the capacitor will discharge so what will be its equation

    eduncle-logo-app

    ok

    eduncle-logo-app

    m attaching see that
