11. It uses resistors to earth to reduce hazards from rail voltages, but the primary return currents are through the rails. 12. The latter system relies on a return current through the ground, using the earth as a second conductor between ground terminal electrodes. 13. The industry has insisted it not only needs free digital licenses but shouldn't be forced to return current channels by a deadline. 14. Grounding is not achieved as the mains power leads are not grounded, but can float around depending on the neutral return current . 15. As tracks for an electric tramway had to be designed to allow for return current , an all-new trackage would have to be laid. 16. Phantom powering as used in audio is a form of simplex powering, as the return current flows through the ground or shield conductor. 17. The problem was exacerbated because the return current also had a tendency to flow through nearby iron pipes forming the water and gas mains. 18. Station lighting used four lamps in series, with return current via the running rails . ( Gas lighting was provided as a back-up .) 19. The sea return current enters the sea at the Sardinian end ( Anode ) and leaves the sea at the mainland end ( Cathode ). 20. On the far side of the figure, the return current flows from the rotating arm through the far side of the rim to the bottom brush.
