Ejercicio Nº5

Para los siguientes circuitos calcular la tensiones y corrientes indicadas (utilizar las leyes de Ohm y Kirchoff) Verificar mediante un programa de simulación de circuitos.
circuito Nro:1

I=?=E/R=6V/(100Ω+200Ω)=0.02A

VR1=?=6V=(E*R1)/(RT)=(600)/(100+200)=(600)/(300)=2V

VR2=?=(E*R2)/(RT)=(6*200)/(100+200)=4V

IR=?=VR1+VR2=2V+4V=6V

CIRCUITO Nro:2

I=5V

V=?=I*R=5*(10+20)=5*30=150V

CIRCUITO Nro:3

IT=I1+I2=2A+2A=4A

I1=E/R1=10/5=2A

I2=E/R2=10/5=2A

CIRCUITO Nro:4

RT=1/(1/R1+1/R2+1/R3)=1/(0.025+0.1+0.05)=1/0.175=5.7143Ω

RT=5.7143Ω

CIRCUITO Nro:5

RT=R1+{1/(1/R2+1/R3)}=5+{1/(1/6+1/4)}=5+{1/(0.17+0.25)=5+{1/(0.42)}=5+2,4=7.4

IT=E/R=10/7.4=1.35A

VR1=(E*R1)/(RT)=(10*5)/(7.4)=6.76V

VRP = 1.35A * 2.4 Ω=3.24A

I1=IT

I2=VRP/R2=3.24/6=0.54A

I3=VRP/R3=3.24/4=0.81A
