The difference between The 2 voltages is due to the fact charging a battery requires a delta voltage (as many as 13–fourteen V for charging a 12 V battery). Moreover, it truly is simpler to do the switching on the line-voltage facet of the transformer due to the decreased currents on that aspect.
Approximately the center from the 10 years, standby electric power was often numerous watts or maybe tens of watts per appliance. By 2010, rules were in position for most produced nations around the world restricting standby power of products offered to at least one watt (and half that from 2013).
