I had one strong doubts Regarding Earthing. I am seen several devices. Earthing is Provided in AC Voltages only. My Doubt is Earthing Factor will comes only in AC Devices or DC Volatage are Required Earthing. If So why we are mention only Positive and Negative Terminals there is No Earthing Terminal. But In AC There will be Phase, Neutral and Earth Terminal?
