What type of current is used in batteries and which is used in household outlets?
In batteries Direct current is used (DC). This is because Batteries do not last very long and therefore are made to have certain voltage that can be used in most electronics. Batteries can be very hazardous if there is a short circuit that occurs. In households the outlets are a form of Alternating current (AC). This is because AC is easier to use and has no big hazards (unless you stick a fork in the socket). If some of the outlets give out (die or burn out) the rest of the remaining sockets in that same area will still work.
