When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in ...

Complex circuits may have some resistors connected in series, and some connected in parallel. For example, the following combination of resistors shows two resistors connected in series, and three ...

Finally a set of digital multiplexers handles an LED to see which of the many resistors is currently selected through a pair of buttons, and a dot-matrix LCD display delivers the value.
