I-transistor iwukhulisa kanjani umyalezo?
I-transistor yakhiwe ngezinto eziziphatha njengama-semiconductor - okusho ukuthi lezi zinto ziqhuba ugesi kodwa kuphela uma kuhlangatshezwane nezimo ezithile. Ngokuhlanganisa lezi zinto zibe idivayisi ebizwa ngokuthi i-transistor siyakwazi ukwakha ingxenye ye-elekthronikhi ezoqhuba ugesi kuphela lapho kufakwa ugesi omncane kulokho okubizwa ngokuthi i-base pin ye-transistor.  Ukusetshenziswa okusobala kokuziphatha okunjalo ukusebenzisa i-transistor njengokushintsha - ngokufaka noma ukususa i-current ku-pin base siyakwazi ukulawula ukuthi i-transistor iqhuba ugesi nge-collector yayo ne-emitter pins. Lapho kungekho gesi ekhona ku-pin Base i-transistor izovimba ukudluliswa kukagesi ngokusebenzisa izikhonkwane zayo zokukhipha nokuqoqa.  Ngokuvamile, amandla kagesi adingekayo ukuze kulawulwe i-transistor esikhwameni esiyisisekelo mancane kakhulu. Imisinga emikhulu kakhulu ingadluliselwa kule divayisi ngezipikili zomqoqi nezomkhiqizi. Ngakho, empeleni, i-transistor isebenzisa amandla amancane kakhulu okufaka amandla ukuze ilawule ukugeleza kwamandla amakhulu kakhulu.  Ngokwesibonelo, isignali yomsindo, idluliselwa njengamandla kagesi aphansi kakhulu - esimweni sayo sokuqala incane kakhulu ukuba ikwazi ukushayela isikhulumi ukuze yenze imisindo ezwakalayo endlebeni yomuntu. Ukuze sikhulise lesi siginali ukuze sisetshenziselwe ukudlala umsindo singasebenzisa isignali yomsindo ku-pin yesisekelo se-transistor - lokhu kuzovumela ukuthi kube nokugeleza okukhulu kakhulu kwamanje phakathi kwe-emitter ne-collector pins futhi nge-transistor. Njengoba ukugeleza kwalokhu kwamanje okukhulu kuzobonisa umfutho omncane kakhulu wesiginali yomsindo sizobe sesidale ngempumelelo inguqulo enamandla kakhulu yesiginali yokuqala yokufaka.
