What are the differences between high and low voltage in electrical systems?

High voltage and low voltage in electrical systems refer to the amount of electrical potential difference present. High voltage systems have a greater potential difference, typically above 1000 volts, and are used for long-distance power transmission and industrial applications. Low voltage systems have a lower potential difference, typically below 1000 volts, and are commonly used in residential and commercial buildings for lighting, appliances, and electronics. The main differences lie in the safety precautions, equipment requirements, and applications of each voltage level.
