Mune chinyorwa chakapfuura isu takatotangisa iyo voltage mugoveri uye ndikatsanangura kuti paive nemasevhisi akawanda uye akawedzera maseketi, senge frequency kana zvazvino macircuit. Zvakanaka ikozvino isu tichaenda kunotsaidzira iyi yekuisa kune yazvino divider. Sezvo iwe uchigona kufungidzira kubva kuzita rayo, iri chaizvo dunhu iro rinogona kupatsanura ikozvino kana kusimba kwedunhu pane zvarinoburitsa kudzikisa kukosha kupfuura iwo akapinda.
Chokwadi ndechekuti aya ese maseketi anogona kushandura mamwe maitiro kuita mamwe, angave ari mawachi frequency, magetsi kana azvino senge mune ino kesi, ndiwo akanyanya zvakajairika uye zvinoshanda kune huwandu hwekushandisa hunogona kupihwa. Uye zvakare, zviri nyore kwazvo kuvaka uye zvakachipa, uye inogona kuve muyedzo wakanaka wevadzidzi vezvemagetsi vanoda kutarisa mabatiro ainoita nemapolymeter ...
Chii chiri chazvino chakakamura?
Un divi razvino, Sekutaura kwandakaita, idunhu iro rinogona kupatsanura hunyanzvi hwazvino huripo pakuisa kwaro kune mamwe madiki masimba pakubuda kwaro. Kuti uwane izvi, panodiwa chete maresitor. Kungofanana nemugadziri wemagetsi wakagadzirwa nema resistor akateedzana, kana iyo yekuwedzera magetsi yaive ma diode muparutivi, iyo yekuparadzanisa irori idanho rematanho akaumbwa neanopikisa anoenderana.
Rangarira: resistors mune akateedzana = voltage divider, resistors mune yakafanana = ikozvino divider
Nekudaro, kana iwe uine muparadzanisi wazvino nematanho maviri kana maviri maresitor mukufanana, yega yega ichave ichishandisa chikamu cheiyo yakazara kusimba. Aya ndiwo maitiro aunowana kupatsanura zvazvino. Mune mamwe mazwi, zvine hungwaru, tarisa pamufananidzo, kana ukangoshandisa zvinodzivirira zviviri chete, ku verenga kuti chii chiri kubuda izvozvi, iwe unogona kupatsanura kushorwa kweR1 neuwandu hweR1 + R2 uye mhedzisiro uiwedzere nekuwanda kwese (kuisa).
Sezvauri kuona, iwe unogona kuverenga izvozvi zvaunazvo padanho rega rega zvinoenderana nekukosha kwema resistor. Uye kana iwe uchida, iwe unogona kuwedzera nhanho kana zvinodzivisa zvakafanana uye nekugadzirisa mafomula kuti uzive yekupedzisira yazvino. Rangarira kuti iwo mauniti anofanirwa kunge ari ma ohms, uye iko kusimba kwemamps ... Nyore handiti?
Nheyo iyo yakavakirwa pairi
Uye mune chii musimboti wakavakirwa kuti ugone kupatsanura zvazvino? Handizive kana iwe wakadzidza zvemagetsi kana kwete, asi kana iwe uchidzidza yakapusa nhevedzano uye yakafanana resistor maseketi, iwe unoudzwa mumanyowani uye mabhuku ekudzidza kuti kana ma resistor akaiswa mune zvakafanana iyo yazvino yakakamurwa nenzira dzinoverengeka.
Kana iwe uchirangarira, nematanho anodzivisa, iwo voltage kana voltage inoparadzirwa pakati pavo (voltage divider), asi iyo yazvino inoyerera nepakati pavo yakafanana neiya yakapihwa. Ipo mukati ma resistor mukufanana iyo voltage inopfuura nepakati peumwe neumwe wavo yakafanana, nekuti magumo avo akabatana akananga kune huru yekupa mutsara. Kune rimwe divi, kana uchitaura nezve kusimba kweakafanana iwo maapu anogoverwa pakati pavo nekuti haatenderedze munzira imwechete senge mune akateedzana.
Ungawana sei ikozvino divider
Wakambozviona here izvozvo kugadzira rwizi rwakaparadzanisa Iwe unongo fanirwa kuve neanopikisa, ita zvakafanira kuverenga sekuratidzira kwandakamboita muchikamu chakapfuura uye tamba nematanho uye kukosha kweanopikisa kuti uwane mhedzisiro yauri kutsvaga. Ichokwadi ndechekuti zviri nyore, handina zvimwe zvakawanda zvekutaura ...
Izvo zvaunofanira kufunga nezvazvo kushandisa, semuenzaniso, potentiometer sezvatakaita nemuparadzanisi wemagetsi. Nenzira iyi iwe unogona kugadzirisa tsika uye kugona kuyedza nemultimeter kuti uone kuti kusiana kwekushora kunokanganisa sei kusimba. Icho chiitiko chekudzidzisa chinoshanda.
Y katsamba kekupedzisira, Kana iwe uchirangarira patakaona iyo yekuparadzanisa magetsi, ini ndakati iko kukanganisa kwakajairika kufunga kuti kana tikaroora zvinhu zvinoverengeka zvinoenderana nekubuda kwavo, hatingave nemagetsi akafanana zvachose. Chikonzero? Rangarira kuti kuramba kwechimwe nechimwe chezvinhu kunokanganisa iwo voltage uye kusimba, muchokwadi, iro divi razvino rakavakirwa pamisimboti iyoyo ...
