S.O.S. Mathematics CyberBoard

Hi, I have been studying linear algebra and I was wondering about its practical uses...

For example, I know how to use matrices in mesh analysis of circuits. This allows me to find current.
However, I heard that by making some simple transformations to current matrix it is possible to find voltage (make voltage matrix or something like that).
Is this true?

Best regard

These ideas come from the laws of conservation of charge and the like. You draw a diagram and note that the system conserves, so the total sums are zero, then you have a system of equations you can use linear algebra on.
