hello DOREENT

if you want Req use parallels and serials .....

 

Will you please show me how? I have no knowledge and looking for help. Will you Please help me by showing how?

 

hello DOREENT

if you want Req use parallels and serials .....

 

for example :
in first circuit ( R7 +R8 +R9 ) serials
and ( R7 +R8 +R9 ) || R5 parallel with R5 .....

Thanks for the tutorial can you work on one of the problems with me so I can get a better understanding?

Can u work on Figure 6-18 for me so I can better understand what you mean. You say R5 is parallel and R7,8,9 is Series but what about other R1,2,3,4?

 

Thanks for the tutorial can you work on one of the problems with me so I can get a better understanding?

I want see your work

 

I want see your work

ok give me about 5mins still working on it by understanding the parallels and circuits on the textbook area ok.

Sorry this is taking too much time for me

ok please let me know am I getting this. If not please assist me with this.

 

am I understanding the concept as what I read/

I am can't see the solution because there is error

my solution for first circuit :

R7 +R8 + R9 = 6.2K ohms

6.2K || R5 = 3.1K ohms

3.1K + R4 +R6 = 8K ohms

8K || R2 =4.8K ohms

4.8K + R1 + R3 = 7.5K ohms

the Req =7.5K ohms

 

I can't see the solution because there is error

me solution for first circuit :

R7 +R8 + R9 = 6.2K ohms

6.2K || R5 = 3.1K ohms

3.1K + R4 +R6 = 8K ohms

8K || R2 =4.8K ohms

4.8K + R1 + R3 = 7.5K ohms

the Req =7.5K ohms

I'm Sorry I understood somewhat something on what you did. Can u help me with Figure 6-19. That is a different diagram from first one then I'm sure I can be able to understand the remaining.

Thanks,
Doreen

Im working on it so If I get some sort of understanding I'll upload my own work for you ok.

Ok great I understand this method better. Can you tutor on Figure 6-19 so I can help myself do the rest. I don't understand that figure for its different from the rest.

 

Outer circuit: R6 and R7 are parallel, and in series with R5 and R8.
Inner circuit: R2, R3 and the equivalent resistance of the outer circuit.
Now, there is just R1, R4 and the equivalent resistance you just calculated.

I'm Sorry I don't understand and still reading on the textbook. Will you please show me the formula and steps that will help me understand better. I do apologize but new to course. Its my first day and class was only 2hrs which covered 4 chapters so I didnt get much on this subject. Please assist me.
