Why Is Voltage Stepped Up Only To Be Stepped Down?
Tom Rafferty2023-09-08T08:57:05-04:00Electrical power has two components, voltage and current. Power = Voltage x Current After power is generated at a power plant, its voltage is increased by a step-up transformer. The power then travels through transmission lines to a neighborhood where it will run homes, offices, and factories. But before entering the neighborhood, the power's voltage is decreased by a step-down transformer. But Why? Why increase the power's voltage only to decrease it later? We want as much power generated by the plant to reach the neighborhood as possible, but we lose some power in the journey. As power travels through the [...]
