Answers
Answer:
In the United States of America the power plugs and sockets are of type A and B. The standard voltage is 120 V and the standard frequency is 60 Hz.
In the United States of America the power plugs and sockets are of type A and B. Check out the following pictures.
Type A: mainly used in North and Central America, China and Japan. This socket only works with plug A.
Type B: like type A but with an extra prong for grounding. This socket also works with plug A.
In the United States of America the standard voltage is 120 V and the frequency is 60 Hz. You can use your electric appliances in the United States of America, if the standard voltage in your country is in between 110 - 127 V (as is in the US, Canada and most South American countries). Manufacturers take small deviations (plus or minus 5%) into account. Be careful if you bring appliances from Japan (100 V).
If the standard voltage in your country is in the range of 220 - 240 V (as is in the UK, Europe, Asia, Africa and Australia), you need a voltage converter in the United States of America. Some say you can carefully try to use your appliances in the United States of America without a converter. Most likely they won't be damaged, but may not function optimally. If you don't want to take any chances, use a converter. You can also consider a combined power plug adapter/voltage converter.
