    what are the examples of current and voltage sources being used in the daily life?

    what are controller sources?

    what is the application of voltage controlled voltage source in our daily life?

    The battery that powers your DVM, that is a voltage source.

    The thing that powers your LED flashlight, that is a current source (even though there is a battery in it....)

    Do you mean "controlled sources"?

    A controlled source is an electrical concept used in circuit analysis.

    Things in real life that behave like a voltage controlled voltage source is an op-amp or audio amplifier.

    Things that behave like a current controlled current source is an NPN transistor or automotive alternator.

    Things that behave like a voltage controlled current source is a battery charger or a JFET.

    Things that behave like a current controlled voltage source is a trans-impedance amplifier or current-limited DC power supply.

    Hello,

    I have merged THREE threads of you with the same intention.
    Please stay in one thread for this.

    What is the concept of gain, transconductance and transimpedance in relation to the controlled sources?
