Short Spanish document on Kirchhoff's laws, the current law for nodes and the voltage law for closed loops. It is a theory sheet rather than a device schematic, and no product or board is named. Those two rules explain why current into a node equals the current out of it, and why the voltage drops around a loop add up to the source. Technicians apply them when working out expected voltages and currents on a rail. At only 19.7 KB, the PDF is likely a few pages of formulas and worked examples.
