When electrons flow between two objects a what is produced?
When electrons flow between two objects, a flow of electric current is produced. This movement of charges generates a magnetic field around the flow of current.
Why does the electric force keep electrons in orbit?
The electric force between the negatively charged electrons and the positively charged nucleus in an atom provides the centripetal force needed to keep electrons in orbit. This force balances the tendency of the electrons to move in a straight line due to their inertia, thus maintaining their circular motion around the nucleus.
What describes the electric forces inside an atom?
Electric forces inside an atom are responsible for holding the nucleus together and attracting electrons to the nucleus. The positive charge of the protons in the nucleus creates an attraction for the negatively charged electrons, keeping them in orbit around the nucleus in specific energy levels. This balance of attractive forces governs the stability and structure of the atom.
Which particles carry an electric current around a circuit?
The particles that carry charge around a circuit are electrons. In some semiconductors, missing electrons in a crystalline structure (of silicon or germanium), caused by adding special impurities, form spaces called "holes" where there is a missing electron. These "holes" can also travel but, in the end, it is electrons that move in the opposite direction to fill those holes that carry the current.
How a body can be charged?
A body can become charged either by gaining or losing electrons. When electrons are transferred between objects, one object becomes positively charged (losing electrons) and the other becomes negatively charged (gaining electrons). This charge separation creates an electric field around the objects.
What is it that travels around an electric circiut?
Electrons
When electrons flow between two objects a what is produced?
When electrons flow between two objects, a flow of electric current is produced. This movement of charges generates a magnetic field around the flow of current.
Explain free electron concept and electric current?
the flow of electrons in semi conductor is called electric current. the electrons revolved around the nucleas is called free electrons

How many shells are there in selenium atom?
A selenium atom typically contains 34 electrons distributed in different shells around the nucleus. The electrons are arranged in energy levels or shells, with the first shell holding a maximum of 2 electrons, the second shell holding up to 8 electrons, the third shell holding up to 18 electrons, and the fourth shell holding up to 6 electrons for selenium.

Why metals conduct electricity?
Metals undergo a metallic bonding, meaning when two metals shares their valence electron they undergo metallic bonding. Within the metallic bond, there are enormous amount of free electrons or what we call " SEA OF ELECTRONS, MOBILISE NOT STATIONARY"constantly moving within the lattice. As we know electrons can carry electric and thermal energy through vibrations and pass the energy from each other throughout the lattice or structure. if u put a piece of metal under the sun light, eventually it will get hot and that's because electrons absorb the thermal energy from sun light and gets excited, the same way " when a guy see a hot girls" and starts vibrating.
What do electrons move around?
Within the electric field of a nucleus, electrons are most likely to be found far outside the nucleus. However, it is NOT the case that electrons are orbiting a nucleus like planets around a star.

Why do electrons have difficulty moving around an Electric Current?
Electrons have difficulty moving around an electric current in certain materials because of resistance. Resistance is caused by collisions with other atoms and impurities in the material that hinder the flow of electrons. This resistance generates heat energy and limits the ability of electrons to move freely through the material.
Compare and contrast The Electric Field Around The Negative Charge And The Electric Field Around A Positive Charge?
A negative charge is caused by a excess of electrons and a positive charge by their lack.
