Circuito 12

 

12. Arma el siguiente circuito. 

Procedimiento

IRA= 1.4mA

RA= R14 + R15

RA= 1000+1000 = 2000 ohms

VRA= 1.4mA *1000 = 1.4 V

VRA= 1.4mA *1000 = 1.4 V

RB=  R27 // RA

RB= R7 * RA / R7 + RA

RB= 1000*2000 / 1000+2000 

RB= 666.66 ohms

RB=2.9V
RB=R4+RA
VRB=VR4=VRA
VR4=2.9V
VRA=2.9V

RC= RB + R44 + R43

RC= 666.66 + 1000 + 1000

RC=  2666.66 ohms

ITC= 12/2666.66 = 4.5mA

VRB = IT *RB = 4.5mA * 666.66 =2.9V

VR9 = IT * R9 = 4.5mA * 1000 = 4.5V

VR10 = IT * R10 = 4.5mA * 1000 = 4.5V

RD= 1/ 1/R7 + 1/R6 + 1/R5

RD= 1/ 1/1000 + 1/1000 + 1/1000 

RD = 333.33 ohms

VRD=VR7=VR6=VR5

VR7= 0.35V

VR6 = 0.35V

VR5 = 0.35 V

 

RE= R8 + RD + R11

RE = 1000 + 1000 + 333.33

RE= 2333.33 ohms

IRE = 2.49 / 2333.33 = 1.06mA

VRD= 1.06mA * 333.33 = 0.35V

VR8 = 1.06mA *1000 = 1.06V

VR11 = 1.06mA *1000 = 1.06V

RF = RE*R1/ RE+R1

RF = 2333.33 * 1000 / 2333.33 + 1000

RF = 699.96 ohms

IRE = 2.49 / 2333.33 = 1.06mA

ITF = 2.4V/1000

ITF= 2.42mA

VRE = VR1 = VRF

VRE= 2.49 V

VR1 = 2.49V

RG = RF + RC

RG = 699.99 + 2666.66

RG= 3366.65 ohms

ITC= 12/2666.66 = 4.5mA

VRF = IT * RF = 3.56mA* 699.96 V

VRF = 2.49 V

VRC=It*RC= 3.56 mA*699.99

VRC=2.49V

VRF=VR1=2.49V

IT = VF / RT = 12/3366.66

IT = 3.56mA

13. Con el procedimiento de ida y retorno, calcula las caídas de voltaje en cada una de las resistencias obtenidas.
