  The table below summarizes information on the electrical systems in use in most countries of the world.
The electric power frequency is shown in the number of hertz (cycles per second). Even if voltages are similar, a 60-hertz clock or tape recorder may not function properly on 50 hertz current.All systems described here usealternating current (AC).

  Adaptor Plugs
A:
   
B:
   
C:
   
This is a plug with two flat parallel prongs. It is used in North America (United States) and in many other countries including Canada, Mexico, Guatemala, Jamaica and Venezuela. This is a plug with two flat parallel prongs with a grounding pin. It is used in the same areas as plug A. This plug is ungrounded and has two round prongs and can be used in most of the countries in continental Europe, & also widely used in South Africa.
D:
   
E:
   
F:
   
This plug is the old British Standard and is used almost exclusively in India & also in wide usage in South Africa. This plug has three larger round pins in a triangular pattern. Plug E is similar to C except it is round and has the addition of a female contact to accept the grounding pin in the socket. This is primarily used in France and Belgium. Plug E is similar to C except it is round and has the addition of two grounding clips on the side of the plug. This is refered to as "Schuko"style and is used in Germany, Austria, the Netherlands, Sweden and Norway.
G:
   
H:
   
I:
   
This plug has three prongs (two flat and one rectangular) that form a triangle, and is widely used in Great Britain. Primarily used in Australia, this plug has two flat prongs like the type A plug, but they form a V-shape rather than being parallel
like A plugs.
This is the grounded version of the Australian plug, this plug has two flat prongs like the type B plug, but they form a V-shape rather than being parallel like B plugs.
J:
   
K:
   
L:
   
This plug is similar to I, but not compatible. It is used exclusively in Isreal. Plug K is similar to C except it is round and has the addition of a grounding pin This is primarily used in Denmark. Plug L is similar to C except it has the addition of a grounding pin This is primarily used in Switzerland.
  M:
   

Plug M is similar to C except it has the addition of a center grounding pin This is primarily used in Italy.
