What are electrons and how are they involved in creating and electric current?
A: Electrons are particles orbiting a nucleus and depending on the material it can have one to many electrons more means better conductor. As a force EMF is impressed on this material electrons are forced to leave orbit and go where ? to the next nucleus but now here there are too many for balance so one leaves and so on. So as electrons flow one way the lack of one goes the other way. basically that is how electrons flow causing electric current as you put it.
Why phosphor screen is used in night vision goggles?
In a night vision tube, the object of the tube is to convert incoming light particles (photons) to electrons. The electrons are then multiplied many times by the microchannel plate inside the tube. It is these multiplied electrons that are the output 'signal'. However, since your eye cannot see electrons, they are converted back to visible light by way of the phosphor screen which 'lights up' when energized by the electrons.
How many valence shell electrons are there in semiconductor atoms?
Silicon, the most widely used semiconductor, has four valence electrons. This places it in between the conductive metals, which have one to three valence electrons, and the non-conductive non-metals which have five to eight valence electrons.
Is current used up?
Current is just a measurement of how many electrons are flowing through a wire in a certain amount of time. The electrons continue to exist, and will continue to flow at their current rate as long as whatever is energizing them continues to have power. So no, current is not used up, but you could describe it as power is being used up, dissipating as heat through the wires and resistors.
