Voltage and current question

  1. Feb 21, 2008 #1
    The voltage is between one phase and neutral. Does it mean that the current flows from the phase line to neutral?

    What do voltage and current mean in terms of fundamental definitions?

    Household wiring uses alternating current. For half of the cycle, the voltage is higher on the hot line than on neutral, and thus current flows from hot to neutral. For the other half of the cycle, the voltage is lower on the hot line than on neutral, and thus current flows from neutral to hot.

    Voltage is analogous to water pressure; current is analogous to the fluid flow caused by a difference in pressure.
