There is a potential difference between the two ends of the generator (i.e. the live wire and the neutral wire). The neutral wire is grounded, which corresponds to a potential of 0, and the live wire becomes 220 V. As for why this is the case, it's because there must be a wire connected To the earth. If it is not grounded it will be very dangerous (both wires have voltage relative to ground).

Introduction The effect of electricity emitted from both ends of the single-phase alternator coil is the same, but why are there still separate live wires and neutral wires, or the beginning and the end? Both ends of the generator (i.e. live wire and zero
