    As resistance dissipates energy in the form of heat and
    Inductor stores in the form of magnetic fields and hence
    Two different energy is obtained by the two

    RESISTANCE:It is the property of the material by which it opposes the flow of current through it. the resistance is denoted by r and measured in ohms.

    INDUCTANCE: It is the element in which energy is stored in the form of electromagnetic field. The inductance is denoted by l and measured in Henry

    When we apply zero volt or ground to the +terminal of an opamp the -terminal also has such low voltage because of high input impedance that is called as virtual ground since it is not ground itself

    When the input nodes of an opamp are taken as ground in the negative feedback condition, then its known as virtual ground.
