    Helllo Everyone,

    question about grounding. I understand that in DC circuit the choice of the reference point is arbitrary. That arbitrary point is also called chassis ground. If that point is physically connected to planet Earth then it is called Earth ground.

    I have recently heard about "ground signal"...What is it?

    Also, why in some circuits we use multipoint grounding? Is good for both AC and DC?

    For instance, in a car, the negative terminal of the battery is connected to chassis. All the other components that are grounded are multipoint grounded?

    Thanks,
    antennaboy
