Question

calcular los siguientes valores paralelos RT IT PT I1P1 I2P2 I3P3 9V R1=120 R2=180 R3=270​

Answer 1

Respuesta:

I1= 0.075 A

I2= 0.05 A

I3= 0.033 A

It= 0.158 A

Rt= 56.84210526 Ω

P1= 0.675 W

P2= 0.45 W

P3= 0.297 W

Pt= 1.422 W

Explicación:

I1= V/R1

I1= 9/120

I1= 0.075 A

I2= V/R2

I2= 9/180

I2= 0.05 A

I3= V/R3

I3= 9/270

I3= 0.033 A

It= I1+I2+I3

It= 0.075 + 0.05 + 0.033

It= 0.158 A

$Rt=\frac{1}{\frac{1}{R1}+\frac{1}{R2}+\frac{1}{R3} }$

$Rt=\frac{1}{\frac{1}{120}+\frac{1}{180}+\frac{1}{270} }$

Rt= 56.84210526 Ω

P1= V*I1

P1= 9*0.075

P1= 0.675 W

P2= V*I2

P2= 9*0.05

P2= 0.45 W

P3= V*I3

P3= 9*0.033

P3= 0.297 W

Pt= P1+P2+P2

Pt= 0.675+0.45+0.297

Pt= 1.422 W
