The Volt is a unit of electric potential. The SI unit of current is the Ampere. You can have very large potential differences (in V) with very small current (in A). The unit of power is the Watt, and 1 W = 1 A*1 V. So, a given power can be obtained using any voltage, with the proper current. In practice, high currents are unsafe so we tend to avoid that in unprotected sockets. Different norms correspond to different tradeoffs. |
