Igwe igwe nkịtị

1. Igwe oyi akwa oyi akwa

A na-emerụ eriri igwe nwere otu oyi akwa n'akụkụ tube akwụkwọ ma ọ bụ ọkpụkpụ bakelite nwere wires akpọchiri akpọchi otu otu.Dị ka eriri eriri antenna ebili mmiri na redio transistor.

2. eriri mmanụ aṅụ

Ọ bụrụ na ụgbọ elu nke eriri ọnya adịghị ejikọta ya na elu na-atụgharị, ma na-agafe n'akụkụ ụfọdụ, a na-akpọ ụdị eriri igwe a na-akpọ mmanụ aṅụ.Na ọnụ ọgụgụ ugboro waya na-ehulata azụ na azụ mgbe ọ na-atụgharị otu ugboro, nke a na-akpọkarị ọnụ ọgụgụ mpịachi.Usoro ikuku nke mmanụ aṅụ nwere uru nke obere olu, obere ike ikesa na nnukwu inductance.Igwe mkpuchi mmanụ aṅụ na-emerụ ahụ niile.Ebe ndị ọzọ na-apịaji, otú ahụ ka ikesa ikesa dị ntakịrị.

3. Ferrite isi na ígwè ntụ ntụ isi eriri igwe

Inductance nke eriri igwe na-ejikọta ma enwere ihe ndọta ma ọ bụ na ọ nweghị.Ịtinye ferrite isi n'ime ikuku-isi ikuku nwere ike ịbawanye inductance ma melite ogo eriri igwe.

4, ọla kọpa isi eriri igwe

A na-eji eriri igwe isi ọla kọpa eme ihe n'ọtụtụ ebe ikuku ultrashort.Ọ dị mma ma na-adịgide adịgide iji gbanwee inductance site n'ịgbanwe ọnọdụ nke isi ọla kọpa na eriri igwe.

5, inductor koodu agba

Inductor nwere akara agba bụ ihe inductor nwere inductance kwụ ọtọ, na akara inductance ya na mgbanaka agba dị ka resistor.

6, eriri igwe kpagbuo (kpagbuo)

A na-akpọ eriri eriri nke na-amachibido ụzọ nke ọzọ na-agbanwe agbanwe ka a na-akpọ coil coil, nke enwere ike kewaa ya na eriri choke nke na-eme ugboro ugboro na obere eriri mkpakọ.

7. eriri mkpuchi

Igwe ihe ngbanwe bụ ibu nke ọkwa mmepụta nke sekit nyocha ihe onyonyo.Igwe nchigharị anya chọrọ mmetụta mgbapụ dị elu, oghere ndọta otu, uru Q dị elu, obere nha na ọnụ ala dị ala.

Kpagbuo omume

Ike electromotive nke na-eme onwe ya n'ime eriri igwe nke inductance na-emegide mgbanwe mgbanwe ugbu a na eriri igwe.Ihe mkpuchi inductance nwere mmetụta mgbochi na AC ugbu a, na oke mmetụta mgbochi a na-akpọ inductance xl, na unit bụ ohm.Mmekọrịta ya na inductance L na AC ugboro F bụ xl=2πfl.Enwere ike kewaa inductors ka ọ bụrụ eriri nkpakọ nke na-eme ihe dị elu na mkpuchi mkpuchi obere ugboro.

Ntugharị na nhọrọ ugboro ole

Enwere ike ịmepụta sekit tuning lc site na ijikọ eriri inductance na capacitor n'otu aka ahụ.Ya bụ, eke oscillation ugboro f0 nke sekit bụ hà ugboro f nke na-abụghị alternating mgbaàmà, otú inductive reactance na capacitive reactance nke sekit bụkwa hà nhata, ya mere, electromagnetic ume oscillates azụ na-apụta na inductance na. capacitance, nke bụ resonance onu nke sekit lc.Na resonance, inductive reactance na capacitive reactance nke sekit bụ hà na-abụghị, na inductive reactance nke ngụkọta akaghị ugbu a bụ nke kasị nta na ugbu a bụ ndị kasị ibu (na-ezo aka AC mgbaàmà na f = "F0").lc resonant circuit nwere ọrụ nke ịhọrọ ugboro, nke nwere ike họrọ akara AC na ụfọdụ
