Majority and minority charge carriers A pure semiconductor has equal number of holes and electrons. But an extrinsic semiconductor has majority charge carriers. When a tri
In a certain binary-star system, each star has the same mass which is 9.4 times of that of the Sun, and they revolve about their center of mass. The distance between them is the 3.
Q State Lenz's law. Lenz's law declares that the induced current produced in a circuit always flows in such a direction that it opposes the change or cause that produces it.
