Medium voltage, high voltage, and extra-high voltage can all have varying effects on the human body depending on the level of exposure. Medium voltage (1kV to 69kV) can cause burns and muscle contractions, high voltage (69kV to 230kV) can lead to severe burns, cardiac arrest, and even death, while extra-high voltage (above 230kV) can result in instant death due to the high levels of electrical energy passing through the body. It is crucial to exercise caution and follow safety protocols when working with or near these voltage levels to prevent any harm to individuals. **
