Why is less resistance for a conductor wire good?
Resistance in a wire restricts the movement of the electrons through the wire. This restriction transfers some of the energy contained in the electrons into the material of the wire and as this energy accumulates in the material of the wire the wire starts to heat. Therefore, there the energy that is transferred into the wire material is considered wasted because it is not available as electrical energy, which means the consumer who is using that wire is charge for the electrical energy that is waste. It the resistance is less in that conductor the consumer will save money.
How does a DC current flow in a wire?
The electrons drift predominantly in one direction.
What term describes signal interference that results from the motion of electrons in a wire?
Thermal noise
What causes a magnetic field to be set up around a wire?
Passing an electric current through a wire will produce an external magnetic field. This is because the electrons have spin and this spin is what produces the field. Spinning electrons (of certain characteristics) also produce the magnetic field of permanent magnets. And no spinning electrons, no magnetic field.
Which of these is a metal wire that allows electrons to flow through it?
Copper wire is a common metal wire that allows electrons to flow through it easily due to its high electrical conductivity.
What particles are moving from atom to atom in a wire?
In a metal wire electrons go and go and go! when conducting electric current.
When a magnet is alongside a wire what happens?
the electrons in the wire begin to flow
How does a wire create resistance?
A wire creates resistance due to collisions between electrons and atoms in the wire's material. These collisions impede the flow of electrons, causing resistance to the current passing through the wire.
Is a statement accurate when i say that a wire carrying more electrons will transfer more energy than a wire carrying fewer electrons?
Not necessarily. The amount of energy transferred by a wire primarily depends on the current flowing through it, not just the number of electrons. The current is determined by both the number of electrons and their speed, so a wire carrying fewer electrons at a higher speed could transfer more energy than a wire carrying more electrons at a slower speed.
What is common wire in a three way when all the wires are black?
If this is a new installation then you have a choice of picking any one you wand to make the common wire. Usually a three wire cable used for three way switching has a white, red and black wire in them. If this is an existing installation and you have misplaced which wire is the common you will have to go back to the switch to find the conductor used. Disconnect it from the switch and temporarily place it on the ground wire. Next go to the next junction box and start ringing the wires to ground. When you find which wire is grounded, this is the common conductor.
What is it called when electrons flow through a wire?
When electrons flow through a conductor such as a wire, it is called, "Electricity".
What happens when electric current is passed through Cu wire?
When electric current is passed through a copper (Cu) wire, the free electrons in the wire start to move in the direction of the current flow. This movement of electrons constitutes an electric current, which generates heat due to resistance in the wire. The wire may also produce a magnetic field around it as the electrons move.
Is a current-carrying wire electrically charged because of the electrons moving in it?
A current-carrying wire is not electrically charged because of the movement of electrons. The wire as a whole remains electrically neutral even though the electrons are moving within it. The flow of electrons is what constitutes an electric current.
Which wire is the common wire in a typical electrical circuit?
The common wire in a typical electrical circuit is the neutral wire.
What happens when a magnet is moved alongside a wire?
the electrons in the wire begin to flow
How does electricity travel through wire?
copper in wires is a metal, and like all metals it is made up of atoms bound together. Basically, atoms are made of a nucleus in the middle, and electrons revolving around the nucleas. In all elements except metals, the nucleus doesn't "let go" of the electrons (unless there is a chemical reaction, but dont worry about that for now), but in metals, the electrons are"allowed to go around" to other nucleuses, electrons are allowed to flow around atoms freely in a metal. It is this flow of electrons that is electricity. however a driving force is needed to make the electrons flow around the copper wire, this comes from a battery or a dynamo.
