What happens when an alternating current flows through a wire?
Within a wire carrying direct current, electrons hop from atom to atom while moving in a single direction. Thus, a given electron that starts its trek at one end of the wire will eventually end up at the other end of the wire. In alternating current, the electrons don’t move in only one direction.
How do electrons move in alternating current?
The electrons in an AC circuit don’t really move along with the current flow. Instead, they sort of sit and wiggle back and forth. They move one direction for 1/60th of a second, and then turn around and go the other direction for 1/60th of a second. The net effect is that they don’t really go anywhere.
Do electrons flow in live wire?
Well because all domestic supply from the mains is alternating current i.e. current that changes polarity and since it is current that changes polarity we can conclude that every time the live wire is positive electrons flow to it and every time it is negative current flows from it!
Does electricity 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.
Do electrons physically move in a circuit?
The electrons do literally move, both in AC and DC. However, the movement of electrons and the transfer of energy do not occur at the same speed. The key is that there are already electrons filling up the wire all along its length. A common analogy for electrical current in a circuit is the flow of water through pipes.
What is the purpose of the neutral wire on alternating current?
Neutral: The white wire is called the neutral wire. It provides the return path for the current provided by the hot wire. The neutral wire is connected to an earth ground.
How does alternating current flow through a circuit?
Because this is alternating current, during half of the cycle the circuit in the live wire is flowing out of the panel, and during the other half it flows in to the panel. Now, the key here is that during the time that current flows out the live wire, it flows back in the neutral wire.
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.
How do electrons move in an AC circuit?
In an AC circuit, the electrons are first “pushed” in one direction, and then “pulled” in the other direction (“pulling” on electrons results in them “pulling” on the electrons “in front”, just like the “pushing” action).
What is the neutral wire in an AC circuit?
In an AC circuit, the NEUTRAL wire is the return for the alternating voltage that flows from the HOT wire.
