what is the advantage and disadvantage of 220 V over 110V in other countries?
Hello dear student !
If you are asking about the advantages and disadvantages of 220 V over 110 V , then it is answered below .
Advantage:
For the same load (power demand) , using 220V basically requires less current than using 110V. So 220V is more efficient than 110V.
Disadvantage:
As higher current can be more dangerous than higher voltage, however , since voltage and amperage are directly proportional. So, 110V wiring is usually considered more safer to work with because it uses fewer volts .
Hope this will help you !
