AC current moves in a wire by periodically reversing direction, flowing back and forth in response to the alternating voltage source. The electrons in the wire oscillate back and forth, creating an electric field that propagates through the wire and carries the energy along with it.
What else can I help you with?
Why does a wire begin to vibrate when ac is passed through it?
When AC (alternating current) is passed through a wire, the current flow changes direction periodically. This change in current flow causes the wire to experience an electromagnetic force that makes it move back and forth, creating vibrations. These vibrations are more pronounced at certain frequencies because of resonance effects.
What is the condition that is necessary for a charge to move in a wire?
The necessary condition for a charge to move in a wire is the presence of an electric field, which exerts a force on the charge causing it to move. This movement of charges in a wire is what constitutes an electric current.
What type of magnetic field do you get around the wire when an ac supply passes through it?
You get building a collapsing eddy currents that alternate in direction. The placing of another wire in this field will cause a current to be generated in the second wire. That is the basis of transformers.
How can you produce current in a wire with a magnet that is stationary?
When a magnet is stationary near a wire, it can produce current in the wire through electromagnetic induction. This happens when the magnetic field from the magnet interacts with the electrons in the wire, causing them to move and create an electric current.
What happens to the charge of a wire when a current flows through it?
When a current flows through a wire, the charge within the wire does not change. The charge carriers (usually electrons) move along the wire, creating an electric current, but the total charge remains constant.
What are the similarities in AC and DC?
Both AC and DC are current methods in which electrons move along a wire
Why does a wire begin to vibrate when ac is passed through it?

Why does the current in a live wire remain positive even when the current may be an ac souce?
I don't think it will. If the source is AC, the live wire will alternate as well.
Why neutral wire does not carry current in closed ac circuit?
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
What are the differences between DC wire and AC wire, and how do these differences impact their performance in electrical systems?
DC wire and AC wire differ in their ability to carry direct current (DC) and alternating current (AC) respectively. DC wire is designed to carry a constant flow of current in one direction, while AC wire is able to handle the rapid changes in current direction that occur in an AC system. These differences impact their performance in electrical systems as DC wire is more efficient for transmitting power over long distances with minimal loss, while AC wire is better suited for powering devices that require frequent changes in current direction, such as household appliances.
Can you use a fusible link wire with 115V AC current?
no
What is the relationship between current and frequency in AC circuit?
Two words: skin effect. Now let's chat. Picture a wire with DC flowing through it. We are going to look at a cross section of the wire without interrupting current flow. Make sense? Picture it. When current flows in a wire in only one direction (DC), it uses all the available metal in the wire. Current flow in the middle of the wire will be about the same per unit of cross sectional area as current flow will be near the outside of the wire. Let's switch our DC for some AC. AC (alternating current) will flow in one direction for a while and then reverse direction to flow the other way for a while. Such is AC. And AC will cause current flow that uses all the available cross sectional area of the wire just as DC does, but only at low frequency. At higher and higher frequencies, current flow in the wire will shift away from the center and be more concentrated near the surface of the conductor. Near the skin of the conductor. AC of higher frequencies will promote current flow by skin effect, and that is the effect of frequency in AC current flow.
What size wire for 250 v AC?
Wire size is not dependent on voltage - it is dependent on current. Please restate your question and provide the expected branch current.
What is generated when a permanent magnet is moved in front of a coiled wire and the magnet's magnetic field pushes and pulls electrons in the coiled wire?
an AC, or alternating current
What is the condition that is necessary for a charge to move in a wire?
The necessary condition for a charge to move in a wire is the presence of an electric field, which exerts a force on the charge causing it to move. This movement of charges in a wire is what constitutes an electric current.
Why does alternating current AC needs thick wire as compare to direct current DC?
The thickness of the wire isn't related to the power being AC or DC; it's related to the amount of power in the circuit. If you are commenting on the wiring in your house you may notice that it's a larger gauge wire but the wire that goes to your lamp is not.
How do you make current?
Move the wire through a magnetic field
