What are semiconductors? Give an example for n-type semiconductors.
Semiconductors are materials having electrical conductivity among that of insulators and conductors. This is because, in semiconductors, there is only a small difference in energy among the ?lled valence band of electrons and the empty conduction band. They are the solids which act as insulator at absolute zero but conduct electricity at ordinary temperatures. For instance, N-type semiconductor is obtained by doping Phosphorous or Arsenic on Silicon or Germanium
what is kinetics
a) Explain the magnetic effects of current? b) Do the diagram to show the direction of motion of the conductor:
As we know that"The electric potential at a certain point inside the electric field is defined as the amount of work done in bringing a unit positive test charge uniformly (without
An alternating voltage is triangular in shape, rising at a constant rate to a maximumof 300V in 8ms and then falling to zero at a constant rate in 4ms. The negative half cycle
