That’s fine for DC current through resistors ... and just work with magnitudes. For simple circuits, this can work, but for something complex (no pun intended), it gets hairy fast.

Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at ...

Simulating a dc-dc converter in LTspice to model closed-loop voltage feedback. LTspice can be utilized to perform statistical tolerance analysis for complex circuits. To show the efficacy of the ...

1) and similar half-wave circuit. The front end of these circuits is ... a more conventional ac-dc circuit would not only increase the PCB area, but would also be quite complicated.
