Resistor: A passive chunk of material that resists the flow of electrical current. A terminal is connected to each end you’re done. What could be simpler? It turns out it’s not so simple at all.

To produce more complex networks whose equivalent resistance is a combination of the individual resistors, individual resistors can be connected together in a series connection, a parallel connection ...

The progress in digitization has profoundly changed our lives. There is no area of everyday life to which digital circuits haven’t penetrated. Ever more powerful microcontrollers and data converters ...
