What is the Difference between an active earth pressure and passive earth pressure?
When the wall moves away from the backfill, the earth pressure on the wall decreases. This minimum pressure is called active earth pressure. On the other hand if the wall moves towards the backfill, the earth pressure increases. This maximum pressure is called passive earth pressure.
What do you understand by technical current direction?
Current in metal conductors is normally termed either 'electron flow' or 'conventional flow'. I'm not aware of the term, 'technical current'.'Electron flow' assumes that current is a flow of free electrons through the conductor, from a negative potential to positive potential.'Conventional flow' (also known as 'Franklinian flow', after Benjamin Franklin) predates what we know about the atom, and was based on the assumption, by scientists such as Franklin, that current was a flow of some mysterious 'fluid' from a higher pressure ('positive' pressure) to a lower pressure ('negative' pressure).Some textbooks assume 'electron flow', whereas most assume (for no accountable reason!) 'conventional flow'. At least one textbook I know of has been published in two versions: an 'electron flow version' and a 'conventional flow version'!
Pressure rating black iron schedule 80?
What medium and temperature as there is something called "pressure temperature relationship"
What is the balance piston used for a centrifugal compressor?
Due to the pressure rise developed through the impeller, a pressure difference exists across the hubs and covers such that the impellers have a net thrust in the direction of the compressor inlet. The balance piston counteracts that by being located behind the last impeller. This is accomplished by subjecting the outboard side of the balance piston to a low pressure from the inlet side of the compressor thereby creating a pressure differential opposite to the direction of the impellers. This pressure is acheived by connecting the area behind the piston to the inlet using a line. The impeller thrust not balanced by the balace piston is absorbed by the thrust bearings. I hope this helps
What pressure or force that causes current flow through a conductor is caleed?
The pressure or force causing current to flow through a conductor is called voltage.
When an electron is displaced in a semiconductor the hole thats left behind is what?
When an electron is displaced in a semiconductor, the hole that is left behind is called an electron hole. Energy can still be conducted because other electrons can and do jump to the space left by a displaced electron.
When an electron is displaced in a semiconductor the hole that left behind is?
A lack of electron
What is an ejected electron called?
An ejected electron is called a photoelectron.
What Atomic particle with a negative charge is called what?
An atomic particle with a negative charge is called an electron.
What is fermi pressure?
This is a guess, but I suspect the person means the electron degeneracy pressure.
What is An atom with one extra electron or one missing electron called?
An atom with one extra electron is called an anion, while an atom with one missing electron is called a cation.
A negatively charged subatomic particle is?
This is the electron.
What is the anti-particle of an electron?
The anti-particle of an electron is called a positron. It has the same mass as an electron but carries a positive charge, making it the antimatter counterpart of the electron. When a positron and an electron collide, they annihilate each other, releasing energy in the form of gamma rays.
What is an escaped electron called?
An escaped electron is called a free electron. These are electrons that are not bound to an atom or molecule and are free to move and interact with other particles.
What is general idea behind the electron transport is?
D, ily Plato
What is an electron that is loosely bound to its nucleus called?
A valance electron.
What is need to study about hole curren when there is actually electron current which is involved?
actually it is the holes which lead to the movement of the electron,as electron moves to the hole's place creating a hole behind.
