    1.How does inductor hold the law of conservation of energy.

    2. How does capcitor & inductor are linear devices?

    3. Lumped matter discipline say rate of change of flux & rate of change of charge should be zero.
    or capacitor I understand this that net rate of change of charge is zero.
    But how does it applies to inductors where flux is involved

    1) How much energy is stored in an inductor of inductance L having a current I flowing in it?

    2) What is the electrical power being supplied to the inductor if it has a current I through and a voltage V across it?

    3) What is the rate at which energy stored is being stored in the inductor under the conditions in #2?

    4) What does it mean for a device to be "linear"?

    5) What are the defining relations for an ideal capacitor and an ideal inductor?

    6) Do they satisfy the requirements in #4?

    7) I can't quite figure out what you mean in your third question. It's probably just a language thing.
