Explain why electric power transmitted at high voltages and low currents to distant places |
| Answer» Wire resistance causes losses in eletric power transmission. If you keep resistance constant, losses are linearly proportional to voltage, but proportional to the square of the current. So if you double the voltage, for the same power you have half the current, and power dissipation is effectively halved for the same power. | |
