Voltage standards are established guidelines that define the acceptable voltage levels for electrical systems and devices. These standards ensure safety, compatibility, and efficiency in electrical applications. Different regions may have varying voltage standards, such as 120 volts in North America and 230 volts in Europe, which are crucial for the proper functioning of appliances and equipment. Organizations like the International Electrotechnical Commission (IEC) and the Institute of Electrical and Electronics Engineers (IEEE) develop and maintain these standards. Adhering to voltage standards helps prevent electrical hazards, reduces the risk of equipment damage, and promotes interoperability between devices from different manufacturers.
