How fast do electric currents move?
Yes, typically about 2/3 of the speed of light in a vacuum - that is, about 200,000 km/sec. Note that the drift speed of the electrons is only a fraction of a millimeter per second, and the random speed of electrons is faster, but still much slower than the speed of the CURRENT.Yes, typically about 2/3 of the speed of light in a vacuum - that is, about 200,000 km/sec.

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.
The net speed of electrons in a wire is about?
560 mph
Do electrons lose energy or speed when they cross over a resistor?
You won't like the answer....but electrons are charge carriers and neither their speed nor their energy has much to do with what happens within an electric circuit.
Why bjt is bipolar?
Bjt is bipolar because in bjt the conduction of current is due to the electrons as well as holes
Which has greater mobility in intrinsic semiconductor Electrons or holes?
The mobility of electrons is always greater than holes. Only the number of electrons and holes would be same in an intrinsic semiconductor.
What is the number of free electrons and holes in a pure semiconductor at 0k?
There are no free electrons and holes in a pure semiconductor at 0k.
How does katniss compara gale and Peeta Mellark?
gales better
What does eres Bella para mi nada compara mean?
you are beautiful to me nothing compares
What is the formula for mobility of electrons and holes?
E=uVd
When a potential is applied to pure germanium in what direction do the electrons and holes move?
in pure germanium there are effectively noconduction band electrons or holes, so they don't move at all.
What is the rotation speed of black holes?
as high as 98.7% of the speed of light
Is it true holes have a mass?
The electrons that are missing have a negative effective mass. So the holes have a positive effective mass.
What term refers to holes and electrons in the operation of a transistor?
current carriers
Anode current in an thyristor is made up of?
Holes and electrons
What are the majority and minority current carriers in an N-type and a P-type semiconductor?
In an N-type semiconductor, majority current carriers are electrons, while minority current carriers are holes. In a P-type semiconductor, majority current carriers are holes, while minority current carriers are electrons.
If a pure Si crystal has a million free electrons inside it how many holes does it have.what happens to the no of free electrons and holes if the ambient temperature increases?
If the crystal is pure Si (no dopants or impurities) then the number of free electrons in the conduction band will be equal to the number of holes in the valence band. Each electron leaves behind a hole when it is thermally excited into the conduction band. If the ambient temp. increases, there will be more thermal energy available which will increase both the number electrons and the number of holes.
