orbital electrons
Describe the relationship of the parts of an electrical current?
I assume you mean Voltage, Current and Resistance. Voltage (E)or electromagnetic force is the electrical pressure or force that forces the electrons through any given circuit Current (I)is the flow of those electrons through any given circuit Resistance (R) is anything within the circuit that would restrict the flow of electrons
What is givin off when electrons in an atom fall to a lower orbit?
Energy (in the form of photons) is given off when electrons in an atom fall to a lower energy level.
An electric current occurs in a circuit when?
An electric current occurs in a circuit when a source of energy (or power, which is energy with a time factor) causes electrons to start slowly moving through the circuit at a speed of a few mm or cm per hour. This allows the quantity that we call charge to race through the circuit at a speed of roughly a million miles per hour, which is what we call electric current. Mathematically defined, electric current is the amount of charge which passes a given point in the circuit each second of time, I = Q/t .The source of energy or power can be as nearby as an energy cell or battery, or can be an electrical generating station located many miles away.
You need a cell in the circuit because?
Assuming you are talking about electrical circuits: "Cell" is the name given for a battery. Without a cell in the circuit, there is no supply of electricity. Therefore there is no electric circuit.
What is energy changes from electrical energy to thermal energy?
For example, in a circuit, the conducting wire will have a resistance to the flow of electrons. As a result, the movement of electrons through the circuit is impeded, dissipating energy, which is given off as heat. Basically, because electrical energy has to do with moving charges, energy is converted to heat when inelastic collisions occur at the atomic level.
Is energy given or taken off with electrons?
It is given off
What is the emission of electrons from a metals surface?
the external energy given to electrons,thier kinetic energy increases.thus electrons move from metal surface
How does electricity give off energy?
Electricity gives off energy through the flow of electrons in a circuit. When electrons move through a conductor, they can transfer energy in the form of heat, light, or mechanical motion depending on the device or appliance being used. This flow of electrons generates energy that can be harnessed for various applications.
How does the increasing the voltage in a circuit affect the energy of the electrons flowing in the circuit?
"How does increasing the voltage in a circuit affect the energy of the electrons flowing in the current?" Answer: The charge of an electron is constant. Every electron has a charge of something like 1.6 x 10^-19 coulombs. (The mass of an electron is also constant which will be important below). When the current in a simple direct-current electrical circuit is 1.0 Ampere there are 6.25 X 10^+18 electrons/second (or 1.0 coulomb of charge) flowing past a given point in the circuit (this is by definition or convention). The voltage (V) is equal to the current (I) times the resistance (R), or V=IR. So, in a simple direct current circuit where the resistance is constant (we will just assume that for the sake of simplicity), if we increase the voltage, the current must increase proportionately. This means the total charge passing a given point in the circuit must increase. This means that more electrons must pass a given point in the curcuit every second. Since the charge of every individual electron is constant there must be more electrons moving past a given point every second.What actually happens to the energy of the electrons flowing in the circuit depends on the geometry of the circuit. If the electrons are forced to travel in single-file (like cars on a one lane road), then in order for more of them to pass a given point every second, their velocity must increase. In this case, their energy would also increase according to the formula for kinetic energy (KE) of a moving particle KE=1/2MV^+2 (or one half the mass (M) times the velocity (V) squared). (This is where we have to remember that electrons are particles with constant mass too.) In this case, the energy increases with the square of the velocity of the moving electrons. However, if the electrons still travel at the same speed but on different paths (like cars on a multi-lane highway) so that more of them can get past a given point every second, then their energy doesn't change. In reality the resistance (R) also generally increases with an increase in voltage (V) so the current (I) may not increase in direct proportion to the voltage but the current will generally increase until too much heat and resistance occurs. The heat generated by such a circuit is proportional to the square of the current which is pretty dramatic.
When excited electrons radiate energy the amount of energy given off is equal to?
The amount of energy given off by excited electrons when they radiate energy is equal to the difference in energy level between the initial and final states. This emitted energy is typically in the form of photons.
What is the definition of high energy electrons and how do they impact the behavior of particles in a given system?
High energy electrons are electrons that possess a significant amount of kinetic energy. In a given system, these electrons can impact the behavior of particles by colliding with them, transferring energy, and causing ionization or excitation. This can lead to changes in the chemical reactions, radiation emission, and overall dynamics of the system.
