Current on ground wire
WebNov 16, 2024 · The current through a resistor is proportional to the voltage across it. Since the neutral is at the same voltage as the ground, both our head and our feet are at 0 V. So the voltage across us is 0 V and therefore the current is 0 A. Share Cite Improve this answer Follow edited Nov 16, 2024 at 23:04 S. McGrew 24.4k 3 28 73 WebOct 15, 2024 · If a resistor is placed across the live and neutral wires, the voltage across the resistor is alternating and thus, the current through the resistor is alternating. It's completely irrelevant to this result if the neutral wire is at 0V with respect to ground. But the wire isn't. You are applying 240v ac to the wire.

WebThe ground, green-colored wire is the safety wire to provide a path of electricity when any metal parts touch the hot or neutral wire. Ex: A motor metal casing is connected to the ground wire. If a hot or neutral inside the motor touches the casing, the casing will be energized, resulting in a “fault current” through the ground wire.
