What is Voltage?
Voltage (electric potential difference) represents the work done per unit charge in moving an electric charge between two points ($V = W / Q$). One Volt is defined as the potential difference across a conductor when a current of one Ampere dissipates one Watt of power ($1 ext{ V} = 1 ext{ W/A} = 1 ext{ J/C}$).
Frequently Asked Questions
Why do high-voltage transmission lines operate at hundreds of kilovolts (kV)?
Electrical power transmission loss is proportional to the square of current ($P_{loss} = I^2R$). Stepping up voltage to 500 kV reduces current proportionally, drastically cutting heat losses over long distances.
