14. Electric energy is generated at a potential difference of 45 kV. It is supplied to a nearby town that requires power of 1.00 GW. The transmission line along which it flows has a resistance of 0.50 Ω . What is the energy loss (in kW) due to heat in the line if the energy is transmitted at 900 kV?

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b. b. at twice the distance, the magnitude of the field is 2b. c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
