<P> The two principal properties of the electric power supply , voltage and frequency , differ between regions . A voltage of ( nominally ) 230 V and a frequency of 50 Hz is used in Europe , most of Africa , most of Asia , much of South America and Australia . In North America , the most common combination is 120 V and a frequency of 60 Hz . Other voltages exist , and some countries may have , for example , 230 V but 60 Hz . This is a concern to travelers , since portable appliances designed for one voltage and frequency combination may not operate with , or may even be destroyed by another . The use of different and incompatible plugs and sockets in different regions and countries provides some protection from accidental use of appliances with incompatible voltage and frequency requirements . </P>
