Gịnị bụ a pnp-transistor?

Transistors - a ọkara eduzi ngwaọrụ, nke ọ na-erughị atọ nkwubi okwu. Na ọnọdụ ụfọdụ, ha nwere ike welie ike n'ịwa vibrations ma ọ bụ tọghata mgbaàmà. E nwere ọtụtụ dị iche iche na aghụghọ nke ndị a ngwaọrụ, na n'etiti ha - pnp-transistor.

Performance na afọ nke transistors

Transistors constructively mere na plastic na metal oriri. Ịtụle dị iche iche na nzube nke transistors, ndị a na ngwaọrụ na-ahọrọ dị ka ụfọdụ kwa. Ka ihe atụ, ọ bụrụ na a transistor maka amplification nke elu frequencies, ọ ga-enwe a elu ugboro mgbaàmà amplification. Ma ọ bụrụ na pnp transistor eji na ugbu a regulator, ọ ga-a elu-arụ ọrụ ugbu a mkpoko.
