Umhloli wamapholamu ofinyelela ku-6 volts

Kuvame ukwenzeka ukuthi kuyadingeka ukuthola ubumbano lwamandla akhona kunoma iyiphi ithuluzi. Ngasungula isisombululo senkinga kulabo abangenawo ama-multimeter. Lesi yi-polarity tester ku-4 diade. Nakhu ukubonakala kwakhe, kuncane impela, ngakho-ke kuzothatha isikhala esincane futhi kuhlale kuza ngokusiza lapho kungekho madivayisi akhethekile.

Sizobhekana nemininingwane

Sidinga:

-I-PC 4 PCS. (Model 1n4001 noma ama-analogues: 1n4004, 1n4005, 1n4007);

-Lodiodes ebomvu futhi eluhlaza;

-Reprovistor ku-1Kom;

- Izintambo;

--aka imali enesibindi;

Sizobhekana nohlelo, uma ufuna ukwenza umhloli kuze kube ngama-3 volts, khona-ke ukumelana kungasuswa ohlelweni:

Kepha sibheka ngqo indlela yokwenza umhloli wama-volts ayi-6

Iya emhlanganweni

Ukuqala, ukufaka ama-LED

Okulandelayo udinga ukukhipha amaminithi ama-LED

Ngaphezu kwalokho, ngokusho kohlelo, sihlanganisa yonke imininingwane futhi sithole inketho ye-3-Volt Tester

Kepha umsebenzi wethu ukwenza umhloli we-volt, ngakho-ke, ukulandela uhlelo, usike i-resistor

Okulandelayo, sikhukhumeza izintambo zemibala ehlukene, futhi konke kungahlolwa.

Ngaphambi kokuhlolwa, sinquma ukuthi iyiphi i-diode enquma ubumbano. Sithatha ibhethri, sazi ubumbano lwayo, futhi sixhumane nomhloli. Yikuphi okuholwa kuzokhanyiswa (uma uxhuma izintambo kahle: bomvu nge "+" futhi mnyama nge "-"), uzosho ukuthi ubukhosi bubonwe kahle.

Umgomo wesenzo ulula lapho ubumbano bubonwa kahle (i-wire emnyama ku- "minus", kanye nocingo olubomvu ku- "Plus") luzokhanyisa i-LED, okukhethiwe ", futhi uma kungenjalo okunye kuzokhanya.

Ngine-LED ebomvu "evimbayo"

Futhi okuluhlaza kukhombisa ukuthi ubumbano aluhlonishwa

Hhayi-ke, lapha uma ungunjiniyela wokuqala we-Radio Radio, bese ngincoma ukwenza lo mhloli, kuzosiza kumaphrojekthi wesikhathi esizayo, nakulesi sibonelo, ungaqonda umgomo wokusebenza kwama-diodes :)
