    could someone please explain the ground concept and the purpose of grounding while doing electronics experiments??in what way does it differ from negative potential?? and can we say that ground potential will be 0v??


    please explain in detail......

    Potential diference has to be across two points, that is, voltage is across two points. The high point is commenly refered to as Postitive, Vss, or High. The 0v, is commenly refered to as ground.

    Devices nood a complete loop to work, meaning that conecting the positive side of a battery alone will not work.

    But devises powered from mains (through a transformer) also have a "EARTH" ground.
    And the circuit "ground" "(0Volts) shouldn't be tied together. Tying earth and circuit ground together is a dangerous thing.

    you r saying that ground and the earth wire of main socket are two opposite extremes....

    Earth ground and the Neutral conductor (think of it as the opposite of the hot wire) on a common household duplex outlet should be at the same potential, it's just that the actual physical connection betwen the two occurs all the way back at the main circuit breaker box.

    Shortbus was talking about an isolated power supply. Where the mains feeds an isolation transformer. So the grounds on the input and output side are NOT tied together.
