Where does the heat come from? The current going through results in heat how? The electrons moving give off heat as going to a lower energy?
Where does the heat come from? The current going through results in heat how? The electrons moving give off heat as going to a lower energy?When two conductors are placed in electric contact, electrons flow out of the one in which the electrons are less bound, into the one where the electrons are more bound.
The reason for this is a difference in the so-called Fermi level between the two conductors. The Fermi level represents the demarcation in energy within the conduction band of a metal, between the energy levels occupied by electrons and those that are unoccupied.
When two conductors with different Fermi levels make contact, electrons flow from the conductor with the higher level, until the change in electrostatic potential brings the two Fermi levels to the same value. (This electrostatic potential is called the contact potential.)
Current passing across the junction results in either a forward or reverse bias, resulting in a temperature gradient.
The majority of the heat on Earth comes from the Sun. The Sun's energy is absorbed by the Earth's surface and then radiated back into the atmosphere, creating the Earth's overall temperature.
The heat in the Earth's core is produced by a process called radioactive decay. This is the breakdown of radioactive elements in the Earth's core, which releases heat as a byproduct.
No, the Earth's internal heat does not contribute to global warming. The heat from the Earth's core is mostly contained within the Earth's interior and does not significantly affect the Earth's overall temperature.
Yes, geothermal energy is considered a renewable source of heat. The heat from the Earth's core can be harnessed and used for various purposes, such as heating homes and generating electricity, without depleting the Earth's internal heat.
The heat from the Earth's core is transferred to the surface through convection. This process involves the movement of hot materials, such as magma, from the Earth's core to the surface, carrying heat with it.
