What Are Volts and Why Do They Matter? | Battle Born Batteries
Mar 10, 2021 · High Voltage Vs. Low Voltage High Voltage. High voltage delivers electricity over long distances. In some applications (such as electricity supplied to our homes via high voltage power lines), a large amount of power transmits over a long distance. The most significant advantage of high voltage transmission is greater efficiency.
