Answer

"120 current" typically refers to 120 volts, which is the standard household voltage in North America (not current itself, which is measured in amperes). This is the voltage supplied to most residential outlets in the United States, Canada, and several other countries. The actual current drawn from a 120V outlet depends on the device connected—a 60-watt light bulb draws 0.5 amperes (60W ÷ 120V), while a 1200-watt hair dryer draws 10 amperes at 120 volts.
