Question $1(1$ point$)$

We have seen how to turn a resistor network circuit into a matrix equation. Your friend loves building circuits and hates math. This friend suggests that rather than using matrix math to analyze circuits, we instead could construct a suitable circuit with independent sources and resistors to be used as an analog computer to solve matrix equations!

Will this work? Is there an equivalent resistor$/$independent source circuit for any real$-$valued matrix equation?

Choose the best answer.

No$,$ there exists real$-$valued matrix equations that cannot be expressed as resistor$/$independent source circuits: matrices with a mixture of positive and negative values in the off$-$diagonal elements, for example.

No$,$ "resistors" and "real numbers" are just social constructs of late$-$stage capitalism keeping the sheeple imprisoned in their own minds.

Yes, every real$-$valued matrix equation can be expressed as a resistor$/$independent source circuit! The synergy between math and nature is beautiful.

Yes, but only on the second Tuesday after a crescent moon.

No$,$ there exists real$-$valued matrix equations that cannot be expressed as resistor$/$independent source circuits: real numbers can have arbitrary precision but circuit elements always have uncertainty.
