SUMMARY

The discussion focuses on determining currents in electrical networks using linear algebra principles. Participants emphasize that when currents are not labeled, they can be assigned arbitrarily in any direction, as the analysis will ultimately reveal their actual values. Key concepts include the application of voltage drops across resistors and the principle of conservation of charge. The conversation highlights the intersection of electrical engineering and physics in solving circuit problems.

Homework Statement



Determine the currents in the various branches.

Then there is a picture of the network which has batteries, resistors, and nodes.

Most of the problems have the currents labeled.

My question is when the currents are not labled how do you determine where to put them and what direction to give them?

Homework Equations


No equations.


The Attempt at a Solution



By looking at the the various electrical networks in the book it looks like you can put the currents anywhere and in any diretion.
 
Physics news on Phys.org
Without the picture, this question makes no sense at all! In any case, it looks like a physics problem to me. The whole point is to find the currents using such physics laws as the drop in voltage over a resistor and "conservation of charge".

I'm going to move this to physics homework.
