Je, nini sababu ya kuwepo kwa makosa makubwa kama haya kwenye kitabu cha physics kidato 4 na 1 cha TIE?

Dabil,
Well this isn't formal conversation it's such a shame that you are courageous enough to write such witless and hateful comment just because someone tried to correct something which will save thousands of kids to grab the true and meaningful concept from the book.

What you did sir is right.

You know, some people do not realize how a wrong 'fact' can cause so much damage in learning. I call these lies; viruses

A simple drawing can impact the understanding of a student and make him/her fail to comprehend real physics behind it.

Tuliokuwa tunasoma na kuelewa tunaujua ubaya mchungu mno wa kufundishwa kauongo kadoogo sana. Wanaokariri hawaonagi hata hatari. Yeye akija kurekebishwa simply anakariri tu upya imeisha. Ila sie wengine sasa, unakuta tumeshajenga na nadharia zetu nyingine kichwani halafu unaiona inabomoka yaaani inauma sana🤕

Asante kwa marekebisho. Wanafunzi wanotice, waalimu wanotice, wizara na TIE wooote wanotice na warekebishe.

Siku hizi dv one za 3 gunia, kuna dogo amepata one ya 3,nikasema nimetest phys kidogo nina miaka 8 ya physics , lakini nagusaga gusaga nikiwa na Mda,
Dogo ni mchache kinoma mpaka unajiuliza iyo A kaipatia wapi?

Kuna tatizo kubwa sana kwenye elimu yetu ndo maana wakubwa ama viongozi wetu hawawapeleki watoto wao kwenye shule za umma.

Wanajua elimu ya huko ni full magumashi

Mimi ni muhitumu wa Phy kutoka chuo Y, nimeweza notice some very serious errors katika kitabu cha physics form one na form four TIE na kujaribu kuwatumia email lakini sikupata any response.

On my personal thought ni kuwa, watoto wanajifunza makosa ya wahariri and not all teachers can notice. Hii Ina maanisha nini katika vitabu vya TIE? Ni pendekezo langu hilo kosa liweze kurekebishwa.

Asante.

For pnp transistor emitter and base region is forward biased lakini ukiangalia mchoro sio sahihi

If ingekuwa ni kosa lingeweza kuonekana ni ndogo but its was serious Grave mistakes...
But sio kosa maybe Rudia tena kusoma vizuri utaelwa
This was Emitter based Junction so mwandishi yuko sawa

No he is not. For emitter base junction P region must be connected to + for it to be forward Biased but it's not.🙏

Mnaingizaje watoto chaka sasa! ndo matatizo ya kuamka asubuhi na kuanza kutafuta vitumbua badala ya kukagua vitabu kuona kama viko sawa.
 
Mnao mpinga Mtoa mada eti kuchanganya Kiswa na Kiingereza HAMNA AKILI, kichwani mmebeba Makebichi..
Majina yenu tuu Mmechanganya Kingereza na Kisukuma...
Rubish kabisa, shenz.

Mkuu Physics nimesoma zamani sana about 25 years ago ndo nilimalizaga Form six Nilisomaga PCB so naweza nikakuchallenge kwamba those drawing are correct based on these facts...
maana nimeona wengi wanasema bila kuonyesha kosa liko wapi na mi naona hakuna kosa for these facts..

Kwanza naomba nikurudishe shule kuhusu part ya Transistor maana we have kujua CBE (collector, Base na Emmiter)

Utanisamehe maana me sio mwalimu ntajitahidi kukuelekeza wewe mwalimu!
  • Emmiter ndo inasupply majority charge carrier kwa Base.
  • Collector hii ipo upande wa kulia wa transistor na kazi Yake kubwa ni kukusanya majority charge carrier hii mara nyingi huwa reverse maana inaweza kupelekwa forwad na backward
  • Base hii ipo katikati kama ntakavyoonyesha hapo chini na iko very lightly doped ili kupunguza recombination ndani ya base ili kuongeza collector current na ni nyembamba sana is very ukilinganisha na emitter au collector ili kusaidia kupitisha charge nyingi....

Kama unavyoona hapa chini ...

Narudi kwenye hoja Yako Kwamba mchoro umekosewa..

Kuhusu PNP...

PNP transistor, holes Ndo majority charge carriers.

Na umesema kweli kuwa katika PNP emitter-base junction Ni forward biased,

Kwahyo hapa huwa ina maana kwamba emitter huwa more positive than the base.
Na hii ndo husababisha holes ku flow kutoka kwenye emitter kwnda kwenye the base.

Kwa upande mwingine collector-base junction huwa reverse biased, hii inamaanisha collector huwa positive zaidi kuliko base. Na hii ndo husababisha hiyo depletion region kwenye collector-base junction. Hicho kma kimshale hapo juu kinachoelekea Upande wa kushoto

IMG-20231018-WA0007.jpg

Sasa...

The holes ambayo huflow kutoka kwenye emitter to the base zinavutwa kwenye depletion region kwenye collector-base junction.

Current inayopita kwenye PNP transistor huwa controlled na base current.

Baada ya ABC nilizokupa ili ukumbuke kuhusu Hiyo Kitu
PNP Sasa naomba nirudi kwenye mchoro uliotoa wewe..

Screenshot_20231017-221927_1.jpg

Ukiangalia huu mchoro unaonyesha emitter current IE.
Na holes zinacdoss into N-type base, na zina combine na electrons.
The remainder cross into the collector region to constitute collector current IC. In this way, almost entire emitter current ita flows kwenye collector circuit.

Sasa hapo shida inakuja wapi mkuu mbona mchoro uko clear ..
Au ulitaka wachore hivi
IMG_20210430_224625-768x405 (1).jpg


But michoro yote miwili huu wa kwNza na wa pili yote ni sahihi
Ndo maana nikasema pitia vizuri mchoro utaona kuwa uko sahihi

Nimefanyakazi ya kuchora vitabu vya kiada vya TIE.

Niligundua hakuna majitu bogus na imbeciles kama hao jamaa.

Serikali imejimilikisha uchapaji wa vitabu vya elimu na kuua sekta ya uchapishaji binafsi nchini. Haya ndo maubunifu ya serikali

Mkuu bora umesema ukweli, kuna namna hii nchi ina watu wajinga, mtu akija na jambo la msingi kabisa wao wanali divert na ishue za kipuuz kabisa na huwez amino ndio hawa hawa wanakuja kuwa wateuliwa wakufanya hizi hizi kazi , Matokeo yake lazima yawe mabaya tu…Thank you man for being honest.

Thanks so much for putting a lot of efforts to give such wonderful explanation,

mchoro wa kwanza haupo sahihi sababu P imekua connected to negative terminal which means direction of holes are supposed to be flowing towards -ve terminal ( attraction force between negative terminal and holes in p type) otherwise polarity rule is dified what do you think about this (attraction force between positive and negative charges is it hard for us to comprehend?)

Also sir for so many decades we've been studying newton first law of motion only in 2023 to be found that the interpretation of it deviated from what he actually meant? What I'm saying it's okay to suggest changes and incase you have some doubts

This suggestions are coming from extraordinary physics candidate.

Wewe si ulianza kumshambulia kwa lugha za dharau na kifedhuli
Next time don't go headfirst like a headless chicken.
Ungejipa muda kufuatilia mchoro au ungemuomba ufafanuzi wa kosa lipo wapi.

Ooh now nimefatilia mchoro kwa makini sana Vizuri kuna kitu nimekiona ..

Na nimegundua vitu vifuatavyo..
Unachosema ni kweli kabisa na nimekiona pia baada ya kufatilia na nahisi kuna vitu nimegundua .
The terminal EB is -+ respectivly and thats wrong...

The termina CB Is negtive direction and hands up mkuu umefatilia kwa umakini sana unadeserve kuwa Mhariri mkuu hapo maana mimi..
nimeoverlook mchoro kwa Haraka haraka bila kuchunguza kila sehemu 👏👏🎉🎉🎉🎉
  • The one who do the Designs and explanation walikuwa sahihi but waliochapa nahisi ni layman hawajui ch9chote kuhusu physics thats Why Wametengeneza Grave mistakes
  • Mkuu hili ni tatizo kubwa sana na nafikiri Kuna haja ya kukagua vitabu vya watoto wetu na kuchunguza wanafundishwa nini hii ya leo imenifanya mwanangu akirudi likizo lazima nikague vifaa vyake vyote
