Chii chinoshandiswa ne-led display capacitors?Seye LED inoratidzira opareta, zvinodikanwa kuve neruzivo uye kunzwisisa kweakasiyana emagetsi zvikamu.
Iyo led kuratidza capacitor igaba rinogona kuchengeta magetsi emagetsi.Inoumbwa nemashizha maviri esimbi ari pedyo pamwe chete, akaparadzaniswa nechinhu chinodzivirira.Zvinoenderana neyakasiyana insulating zvinhu, akasiyana capacitors anogona kugadzirwa.Zvakadai se: mica, porcelain, bepa, electrolytic capacitors, nezvimwe.
Panyaya yemaitiro, akatungamira ekuratidzira masikirini akakamurwa kuva fixed capacitors uye variable capacitors.Iyo capacitor ine kusingaperi kushorwa kuDC, ndiko kuti, iyo capacitor ine DC inovharira maitiro.Kupokana kwecapacitor kune alternating current kunokonzerwa nehuwandu hwekuchinjana ikozvino, kureva, capacitors ehumwe simba hunopa maitiro akasiyana-siyana ekugadzirisa kushanduka kwemhepo yakasiyana-siyana.Sei zviitiko izvi zvichiitika?Izvi zvinodaro nekuti iyo capacitor inovimba nechaji yayo uye yekuburitsa basa kuti ishande, kana iyo simba switch s isina kuvharwa.
Iwo maviri simbi mahwendefa e-led kuratidza capacitor uye mamwe mahwendefa esimbi akajairwa haana kubhadhariswa.Kana chinja S chavharwa, maerekitironi emahara ari pandiro yakanaka yecapacitor anokwezvwa nechitubu chemagetsi uye anosundirwa pandiro yakaipa.Nekuda kweiyo insulating zvinhu pakati pemahwendefa maviri ecapacitor, maerekitironi emahara kubva mundiro yakanaka anoungana pandiro yakaipa.Positive plate inochajiswa zvakanaka nekuda kwekudzikira kwemaerekitironi, uye ndiro isina kunaka inochajiswa zvisina kunaka nekuda kwekuwedzera zvishoma nezvishoma kwemaerekitironi.
Pane mutsauko unokwanisa pakati pemahwendefa maviri eiyo LED kuratidza capacitor.Kana iyi inogona mutsauko yakaenzana nemagetsi ekupa magetsi, kuchaja kwecapacitor kunomira.Kana simba rikagurwa panguva ino, iyo capacitor inogona kuramba ichichengetedza magetsi ekuchaja.Kune capacitor yakachajiswa, kana tikabatanidza mahwendefa maviri newaya, nekuda kwekugona mutsauko pakati pemahwendefa maviri, maerekitironi achapfuura nemuwaya uye achidzokera kune yakanaka ndiro kusvika mukana unobvira pakati pemahwendefa maviri wazero.
Iyo inotungamira inoratidzira capacitor inodzoserwa kune yakarerekera nyika pasina muripo, uye hapana ikozvino muwaya.Iyo yakakwira yakawanda yealternating ikozvino inoshandiswa kune mahwendefa maviri e capacitor inowedzera nhamba yekubhadhara uye kubudiswa kwe capacitor;iyo yekuchaja uye yekuburitsa ikozvino inowedzerawo;kureva kuti, iyo inovhiringidza mhedzisiro ye capacitor pane yakakwirira frequency alternating current yakaderedzwa, kureva kuti, capacitive reactance iduku, uye zvinopesana Capacitors ane guru capacitive reactance kune yakaderera-frequency alternating current.Yekuchinjanisa ikozvino kwema frequency akafanana.Iyo yakakura kugona kwemudziyo, iyo diki iyo capacitive reactance, uye idiki iyo inogoneka, yakakura iyo capacitive reactance.
Mukugadzirisa, yakakamurwa kuva fixed capacitors uye variable capacitors.Iyo capacitor ine kusingaperi kushorwa kuDC, ndiko kuti, iyo capacitor ine DC inovharira maitiro.Kupokana kwecapacitor kune alternating current kunokonzerwa nehuwandu hwekuchinjana ikozvino, kureva, capacitors ehumwe simba hunopa maitiro akasiyana-siyana ekugadzirisa kushanduka kwemhepo yakasiyana-siyana.Sei zviitiko izvi zvichiitika?Izvi zvinodaro nekuti iyo capacitor inovimba nechaji yayo uye yekuburitsa basa kuti ishande, kana iyo simba switch s isina kuvharwa.
