Why do some countries use 220 volts?
Cost was the main reason Europe went with 220 volts (now 230). Counterintuitively, higher voltages allow the use of thinner wire, meaning less copper in the early days of power lines. Power companies could save money on wire by using 220 volts rather than 110.
Tenendo presente questo,, why is 220v cheaper than 110v?
The point often noted for the money saving argument is that the amperage is half as much when running grow lights on 220 volts instead of 110 volts. On a 220 volt circuit, the load is split between two 110 volt wires. This allows you to run smaller wire. This brings us to the "probably" part of the answer. What does a 220 outlet look like?
Di conseguenza,, how do i know if my outlet is 240v?
How to Identify 240-Volt Outlets? The 240-volt outlets are larger than 120-volt outlets, and they have rounded tops with three or four holes. The top hole of an older three-prong 240-volt plugs looks like a backward 'L'and the other two holes are diagonally placed on the sides. Tenendo presente questo,, how do i convert volts to watts? The formula to convert voltage to watts is watts = amps x volts.
How many volts is 1000 watts?
Divide 1000 watts by 10 amperes and the resultant voltage would equal 100 volts.
