1-rasm. Kuchlanish va tok manbasining tashqi tavsifini o‘rganish printspial sxemasi



Dastlabki hisoblashlar Variant №3 E2=4.5V.

- zanjirning tokini hisoblash:

=8.18mA =3mA

=7.5mA =1.2mA

=6.4mA =0.8mA

=4.5mA

-yukdagi kuchlanishni hisoblash

=8.18*50=0.4 V =3*1000=3V

= 7.5*100=0.75 V =1.2*3000=3.6V

=6.4*200=1.28 V =0.8*5000=4V

=4.5*500=2.25V
