General Science / Neutral has 0 voltage, so how does current flow?
« on: 15/01/2018 15:12:48 »
Im having trouble getting my head round why it is that:- the neutral in an AC system has 0 volts flowing (in respect to earth), then how does current travel through the neutral cable back to the transformer without any voltage pushing it.
I understand that a voltage is needed to propel the moving electrons (current) around a circuit, from its source, through a load, and back to the source via neutral.
Is it that there really is a voltage in the neutral, but as the neutral is at earth potential, it registers as 0 volts ??
