Consider the voltage. The second consideration is voltage, or the pressure under which current flows through an electrical system. While most U.S. appliances work at 110 volts, many foreign power companies generate electricity at 220 volts. Some appliances have a toggle switch that allows them to work with both voltages, but for non-dual voltage appliances, you'll need a converter to step down the 220 electric current to 110 so your appliances won't burn out.
A common voltage for flashlight batteries is 1.5 volts (DC). A common voltage for automobile batteries is 12 volts (DC). Common voltages supplied by power companies to consumers are 110 to 120 volts (AC) and 220 to 240 volts (AC). The voltage in electric power transmission lines used to distribute electricity from power stations can be several hundred times greater than consumer voltages, typically 110 to 1200 kV (AC).
