Actividad

Determinar la intensidad total y la Resistencia equivalente de los siguientes circuitos.


1.

Resistencia:

Req= 6.8*1.5/6.8+1.5 = 1.22Ω

ReqT= 1.22+4.7 = 5.9Ω

Intensidad:

I1= 9/4.7 =1.9
I2=9/1.22 = 7.4
IT= 9.3 A


2.


Resistencia:

Req= 6.8*1.5/6.8+1.5 = 1.22Ω

ReqT= 1.22+4.7 = 5.9Ω

Intensidad:

I1= 9/4.7 =1.9
I2=9/1.22 = 7.4
IT= 9.3 A


3.
















Resistencia:

1/Req= 1/4.7+ 1/6.8+ 1/1.5 =  10.2/47.94+ 7.05/47.94+ 31.96/47.94
1/Req= 48.21 /47.94
Req= 47.94/48.21
Req= 0.99Ω

Intensidad

It= 9/0.99= 9.09A
