    "All properties are supplied from the National Grid which is ac only so you are getting confused with dc bits in appliances etc"

    "Dc means direct current it flows in one direction and its like the current store in cell battery,
    Ac means Alternating current. It flows in any direction. It's dangerous to work on it. Before any electric work isolate electric current from the consumer unit or old system fuse box."

    "You generally wouldn't have direct current in your home as the power supply coming from national grid is distributed through alternating current, but you would usually see direct current being used on rail tracks or extra low voltage circuits etc. Train track voltage of 750v dc. In properties the standard voltage is 230v ac. Difference is, dc current holds you & ac current throws you. Overhead line voltage is 25000v."
