How do two conductors have different currents even though the electrons in each conductor are travelling at the same speed?

There is a larger volume of electrons moving in the one that has the most current.

A conductor differs from an insulator in that a conductor is an?
A conductor is a material that has one or a few electrons in the outer shell of its atoms. These electrons are easily knocked loose, or are already moving about in the material. When a voltage is applied to a conductor, these electrons are repelled by the negative polarity and attracted by the positive polarity. Their movement is called "current". a conductor is a material that transports electrons and electricity can pass through it, metals are good conductors. a insulator is something that is a barrier to electrons and can not pass electricity, rubber is a good insulator.
Is the looseness of outer electrons in metal atoms the reason metal is both good heat conductors and electrical conductors?
They carry energy from one part of the conductor to another.
Do good conductor causes fire?
Yes, good conductors can cause fires. This is because they have valence electrons which will help move the fire to the other sources.
How does conductors allow heat to go through?
Heat energy can be transfered through a conductor or medium, in three ways. Radiation, which is how the sun transfers energy, through waves. Convection, which is how wind works, the transfer of heat by mixing particles together. Conduction, which is how your hand warms up when someone touches it. The particles transfer their heat energy to adjacent particles.
Why are some metals better conductors than others?
The number of free electrons in a given volume is different for each metal; many electrons is good conductivity.
Materials with many free electrons are considered what?
Electrical Conductor
Can electrons flow in conductors?
It depends on the conductor. Usually yes.
Is sodium a conductor of electricity?
The same reason that all conductors are conductors: it has a lot of free electrons.
How many valence electrons do conductors such as copper have?
good conductors have only one or two electrons in the outer shell while insulators have many more, around eight
What materials do electrons easily move through?
A conductor. The property that determines whether a material is a conductor or an insulator is how tightly bound the outer shell electrons are. Atoms with loosely bound electrons are good conductors. Three examples of good conductors are gold, silver and copper.
Why are conductors electrons able to move throughout a conductor?
Because they are bound loosely
Why does metal attract electricity?
because they are conductors and conductors allow the electrons to flow around freely in the object (conductor). and also, why not?
What is a material that allows electrons to flow easily through it?
Anything that is classified as a conductor will allow the flow of electrons.
What makes an object conductor?
A conductor has low electronegativity and has 3 or less electrons in the outer shell of the atom. Conductors let electrons run through them with little to no resistance.
Why does a semiconductor have fewer electrons than a conductor?
Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.
Are all objects considered conductors?
Assuming you mean an electrical conductor, No. To be a conductor, a material must have free electrons in the conduction band of the atoms. Metals have free electrons intrinsically in these bands, and so make great conductors. If you mean heat conductors, the answer is also no. Some objects are insulators of heat.
How are conductors and insulators different give an example of a conductor and an insulator?
conductors, such as metals, have free electrons, meaning their electrons are not strongly bonded to the atoms and a charge can move easily throughout the whole object, an insulator such as wood does not have free electrons so a charge is likely to stick in one area of the insulator.
