# High Voltage
Who / What
High voltage refers to an electrical potential that exceeds a threshold level capable of causing injury or damage. It is a critical concept in electrical engineering, where voltages above specific nominal limits (e.g., 1000V AC for low-voltage systems) require specialized safety measures and equipment design.

Background & History
The term "high voltage" emerged within the context of electrical power transmission and industrial applications during the late 19th century. Early experiments in electricity, such as those by Thomas Edison and Nikola Tesla, laid foundational work on voltage levels and their practical use in power distribution systems. The concept solidified as engineers developed safer and more efficient ways to handle elevated voltages for long-distance electrical transmission, reducing energy loss and enabling modern infrastructure.
