If high voltage is so dangerous, why do we transmit electricity that way?
Transmitting power at higher voltages ensures that power can be transmitted over long distances with minimal losses; if transferred at a low voltage, the transmission distance has to be greatly minimized, which is impractical.Read More...

Keywords: transformer, voltage
Electrical energy is transmitted at high voltage. Which element creates the 120 V that is available in our wall plugs ant home?
Transformers operate on principles of electromagnetism to step up and step down voltages. This allows for efficient transmission of power across the grid to homes and buildings. It also ensures that the voltage from our sockets is appropriate for home and appliance use.Read More...
