I need to use the node tension method to find the resistance in the traditional resistor cube. Please its for my university class, im from Mexico. Hope someone can help.

 

Did you read the sticky post at the top of the forum?

This is not a place where someone will do your homework for you.

You should show your own attempt to solve the problem, then someone will help you.

 

Yes i read the sticky note, i am trying to do this for a long time, i was investigating too on the internet and found some solutions but with other methods, i dont want somebody to do the homework for me, i just one someone who can point me in the right direction.
Thankyou.

 

Classic case of if you're intending to become an academic, or a practical 'hands on' engineer/tech.
If it's the latter, then spend $1 and build one - and use a meter to measure the real answer. Then try to figure out the maths to check your answer.

If you find that too difficult, then stick with finding practical answers to real world problems, and use the maths you need from those who have already figured out those answers.

If you can figure out the maths, then you might stand a chance of gaining enough qualifications so that you can become an 'engineer' without getting your fingers dirty!

Just don't give up if your maths aren't good enough. The world has already lost too many good potential 'engineers' because their brains weren't naturally wired up to pass the 'maths' exams!

 

Have a look at this thread:

Do you know how solve circuits using the nodal method?

 

I have to write this in MARIE Assemble Code:

M = 1;
N = 1;
while M < 16
{ M = M + N:
N = N + 1;
} end while

This is what I have: Can you please make adjustments as needed. Thank You in Advance!!

A little bit of Googling usually gets the answer. Look at:-

I go for the logical reasoning method myself!
