Olee otú a transistor?

Ozugbo a na-akpọ transistor redio, ma anyị bụ ndị a anyị isiokwu na-aga na redio. N'ihi ya, ihe ọ na-transistor na otú ọ na-arụ ọrụ.

E nwere a na klas nke ihe maka ha Njirimara akpọ Semiconductors. The iche mma bụ ha conductivity - o nwere ike ịbụ ka a eduzi eletrik, na dielectrics, i.e. insulators na-adịghị akpa àgwà na ọkụ eletrik.

Ebe a bụ ihe onwunwe iji ime ka transistor - a okporo ọkụ ngwaọrụ, nke na ọtụtụ-eji ụlọ ọrụ na-eje ozi na ndabere nke fọrọ nke nta niile n'oge a ngwá electronic.

Enweghị emetụ n'ichepụta technology, transistor ụdị, ha ngwa, dị nnọọ mara na e nwere dị iche iche nke transistors, e.g., npn transistor. Nke a aha e nyere ya n'ihi nke eji eme ihe na ụdị conduction. Gịnị ka e kwuru na tupu bụ iji na-aga n'ime mmepụta technology na a dịgasị iche iche nke transistors agaghị.

Olee otú a transistor? Ọ bụ iji na-achịkwa eletrik, structurally mere na a metal ma ọ bụ plastic ụlọ na e nwere ihe atọ ọnụ, a na-akpọ emitter, isi, mkpoko. Dị ka aha na-ekwu, Nchoputa a họpụtara ha: emitter ewepụtarịrị electrons, ha isi njikwa, na mkpoko nakọtara ha. All ndị a Filiks-ebe n'ime transistor.

Iji ghọta otú nke transistor, tụlee a nnọọ mfe atụ - tap.

Ọ na-nwere atọ ọnụ - otu otu na mgbata mmiri aga, dị iche iche wụsara si tap, bụ a atọ valvụ nke akara ahụ ọrụ nke kreenu. Mgbe valvụ na meghere, mmiri aga kpamkpam site na valvụ mgbe valvụ na-emechi, mmiri na-adịghị eru. Nke a bụ ihe na-eṅomi nke onye nke nhọrọ nke otú transistor arụ ọrụ. Nke a mode nke ọrụ a na-akpọ Keyword - transistor meghere - eru eletrik, ma ọ bụ na-emechi, mgbe nke ugbu a adịghị aga. Iji mepee na isi nke transistor na-ume mgbe voltaji bụ, transistor bụ oghe, ma ọ bụrụ na ọ bụghị, mgbe ahụ, ọ na-emechi. Ihe niile na-eme dị ka ndị foset, valvụ bụ oghe - mmiri aga, valvụ na-emechi - miri.

N'elu na e weere ya na transistor mgbe ọ na-eji dị ka a isi, ma na-emechi ma ọ bụ na-emeghe. Otú ọ dị, e nwere ndị ọzọ ụdịdị nke ime. Ọzọ ihe atụ, tụlee ihe mgbata. Ọ bụrụ na a obere ka ubé emeghe valvụ, na mgbata mmiri ga-asọpụta nọgidere na mmiri mgbali ga-ekpebisi ike site na otú ihe anyị meghere tap.

Banyere otu ọrụ n'ebe ahụ transistor. Na ya isi na-enweta ihe voltaji, ọ ga-emepe, na site na ya bụ ugbu a. Site mgbanwe ịdị ukwuu nke voltaji na isi ike na-achịkwa ego nke ugbu a na-eru site na transistor. Complete ntụnyere na ọnọdụ nke valvụ na foset karịa bụ na-emeghe - ọzọ aga nke mmiri (i.e., a ugbu a maka transistor); obere oghe - obere mmiri eru (ugbu a maka transistor). Nke a transistor a na-akpọ ihe ana-akọwa ọrụ mgbe eji a obere voltaji etinyere isi ike na-achịkwa ịrịba ugbu a, a mbughari esite.

Ná mmechi, ọ ga-kwuru na transistors nwere ike dị iche iche, ha niile kpebisie ike na mgbe ihe na-eji ya emepụta. Ha nwere ike iche na ikike, nwere ike ijikwa na-agabiga a ọkpụrụkpụ eruba nke eletrik. The transistors nwere ike dị iche iche ngwa imewe. E nwere ndị ọzọ ụdịdị nke transistors ndị dị iche na-atụle. Ma echiche bụ isi nke otú transistor e nyere n'elu.

Ihe niile na-anọwo na, ma ka na-eme ka o kwe omume na-aghọta na ime ihe nke transistor. N'ezie, transistor n'ezie bụ ihe ndị ọzọ siri ike. E nwere ihe pụrụ iche na ntọala, nke i nwere ike iji formulas gbakọọ na ịtọ chọrọ mode, ma nke ahụ bụ a isiokwu mkparịta ụka ọzọ isiokwu.
