Does current flow from live to neutral?
Yes an “alternating current” from One wire to the load and back through another. Since it is alternating current saying that it flows from Live to Neutral or Neutral to live is one and the same thing. We normally say it frows from Live to neutral because the neutral is always at Zero Voltage w.r.t Earth.
Does current flow through live wire?
If there is a fault that causes the casing of the device to become live, a large current will flow through the live wire and low-resistance earth wire. This high current will cause the fuse to melt. Once the fuse has melted, the circuit is broken and no more current flows through the device.
Why does a neutral wire show current?
Each house is connected to a single phase Line, the return current travels back to the transformer via the Neutral line. So whatever current flows in the supply line also passes through the neutral. The neutral wire in a circuit carries the same current as the hot wire. Current goes out to the load and must return.
Is neutral wire live?
In a plug, the live wire (brown) and the neutral wire (blue) are the two wires that form the complete circuit with a household appliance.
What happens when live and neutral wires touch?
The neutral wire is touched by the live wire. The path from the live to the neutral wire has very low resistance and will create a short circuit if the large current exceeds the fuse rating. There will be a blow.
How does electricity flow through a refrigerator?
The electric current flows from the power source, along the active or live wire, through the fridge, and back to the power source through the neutral wire. In modern installations there is usually a balanced current detector which protects against electric shock and other leakages to earth.
What happens when current flows through the neutral wire?
The neutral wire completes the circuit, giving a return path for the current. Similarly, when the current flows in the live wire, it flows out the neutral. At any given time, whatever current flows through the live wire, an equal amount (*note 2) flows in the opposite direction through the neutral wire.
What happens when the voltage of Live Wire is more positive?
It is presumed by the convention we follow that when the voltage of live wire is more positive than neutral the current flows from live wire into appliance and back through neutral wire. When voltage of live wire is more negative than neutral then the direction of current is reversed.
How does current flow through an electrical circuit?
The “live” wire will have positive and negative voltages (periodically) with respect to the neutral (and therefore with respect to ground as well). The current will flow from neutral to live (through your electrical appliance, thus providing energy) for some period of time, and then change direction and flow the other way.
