List of worldwide ac voltages and frequencies
The voltage and frequency of alternating current (AC) electricity used in homes vary from country to country. Typically, either 120-volt or 240-volt alternating current is used.
The majority of countries use 50Hz (50 Hertz or 50 cycles per second) as their alternating current frequency. Only a few use 60Hz.
The standard in the United States is 120V and 60Hz AC electricity. The average measured voltage is 117V AC due to fluctuations.
What is the electrical rating of various countries?
The majority of the over 200 countries listed below use 220-240 VAC. Others use 100-120 volts. Dual voltages are used in some countries, including the United States. The majority of countries use 60Hz, while the rest use 50Hz.

Conclusion
The voltage and frequency of alternating current (AC) electricity vary from country to country around the world. The most common voltage and frequency are 220V and 50Hz. Around 20% of countries power their homes with 110-120 V and/or 60Hz. The most efficient values are 220-240 V and 60Hz, but only a few countries use that combination. The United States uses 120V and 60Hz alternating current (AC).
