How does electric third rail work
WebCircuit does complete. In all Generating and T&D stations, one terminal is always kept grounded, so that it makes the supply voltage fixed at certain value (typically 11 kVAC worldwide standard for generation, 440 kVAC for long distance transmission). Basic requirement is a potential difference and grounding through the rail achieves that.
