Which subatomic particle is free to move?

Electrons are free to move within an atom and between atoms, making them the subatomic particles that can easily move. Electrons are negatively charged and are responsible for the flow of electric current in conductive materials.


Electron current flow theory considers electricity to be the flow of charge carries which are what in polarity?

When we consider electron flow, we think of moving electrons. The electron has a negative charge. This model of current flow, the electron current flow model, follows the movement of those negative charges.As a contrast, we might consider what is called conventional current flow. And that the model of current involves the movement of charges with a positive polarity.


What is the difference between electron flow and conventional current?

We all know that, in metal conductors (but not in other conducting media), free electrons slowly drift from the negative end of the conductor to the positive (or 'less negative') end of the conductor. But before anyone knew about atoms, an electric current was thought to be the flow of some sort of 'fluid' from a higher pressure (i.e. positive pressure) to a lower pressure (i.e. a negative pressure) -as suggested by Benjamin Franklin. This error was reinforced by Michael Faraday as a result from his experiments in electrolysis.So 'electron flow' (- to +) describes what is actuallyhappening in a metal conductor, whereas 'conventional flow' (+ to -) is, to put it simply, an error!Unfortunately, because so many 'rules' that relate current direction to the direction of magnetic fields and electric fields were based on conventional flow, many textbooks have found it convenient to stick with conventional flow.


What instrument can be used to detect electron flow?

An ammeter is commonly used to detect electron flow in a circuit. The ammeter measures the amount of current (flow of electrons) passing through a specific point in the circuit.


How do electrons in conductors move about freely than the electrons in insulators what?

Electrons in conductors, such as metals, are loosely bound to their atoms and can move freely through the material, facilitating the flow of electric current. In contrast, electrons in insulators are tightly bound to their atoms and do not have the ability to move freely, which prevents the flow of electric current. This difference in electron mobility is due to the varying atomic structures and energy band gaps in conductors and insulators. As a result, conductors allow for efficient electron transport, while insulators resist it.

Why does metal make a good conductor and rubber does not?

Metal makes a good conductor because its electrons are free to move easily between atoms, allowing for the flow of electricity. In contrast, rubber is an insulator because its electrons are tightly bound to their atoms, making it difficult for electricity to flow through.


What specifically does resistance reduce the flow of?

Resistance is the opposition of the atoms in any materiel to the movement of the electrons of a certain current ... so the resistance is a long wire, and thus more atoms to pass through that's how it reduces the electron flow


Difference between electron flow and conventional current?

Conventional current flow refers to a flow of positive charges. It is a kind of ficticious current. If - as is often the case - the real current is an electron flow (negative charges), then the conventional flow is a current in the opposite direction as the electron movements, since this would have the same effect (for example on the magnetic field, or on conservation of charge).


Is the flow of electrons?

Electron flow is what we think of as electrical current. We are familiar with two types of electron flow, Direct Current, or DC, and Alternating Current, or AC. Direct Current is the kind of electrical flow we get from batteries and solar cells, when electrons travel in only one direction. On the other hand, AC is the kind of electrical flow we get from a typical electrical outlet in a home. AC is when the electrons flow in two directions, from the positive to the negative terminal and from the negative to the positive terminal, 'alternating' between the two directions. (Your lights will light up regardless of the direction of the electron flow.) A lot of people think of electron flow as electrons moving along a wire freely like cars go down a highway. Actually, it works a little differently. Any conductor (thing that electricity can go through) is made of atoms. Each atom has electrons in it. If you put new electrons in a conductor, they will join atoms, and each atom will spit out an electron to the next atom. This next atom takes in the electron and spits out another one on the other side.

What energy is the flow of electrons?

Flow of an electron will contain how much current?

1.6x10^19 amperes is the amount of current that a flow of an electron will contain.


Why do atoms give us electricity?

Electrons can be made to move from one atom to another. When those electrons move between the atoms, a current of electricity is created. The electrons move from one atom to another in a "flow." One electron is attached and another electron is lost.


How could you slow down electron flow?

You can slow down electron flow by increasing resistance in the circuit, using resistors for example. By increasing the obstruction to electron flow, you reduce the rate at which electrons can move through the circuit. Additionally, lowering the voltage in the circuit will also slow down electron flow.


What is the unit for measuring the rate of electron flow in a circuit?

Electron flow is known as current. SI unit is Ampere


What is the current?

Current is defined to be a flow of electrically charged carriers. These are usually electrons or electron-deficient atoms. It is symbolized by uppercase letter I.


What flow is equal to and opposite of electron flow?

The "flow of current" is considered to be in the opposite direction.
