Simple series circuits can lead to not-so-simple problems.

Simple electrical circuits are super cool, but simple series and parallel circuits are just the foundation of the much, much more complex circuits used in modern electronics.

A simple series resistor circuit should suffice. Fig. 7 is a classic voltage divider. The output voltage will be at half of the input voltage, which is 6 dB lower than the input. Fig. 7: Voltage ...

Researchers recently tackled a simple circuit in the visual processing area of a chicken's brain that detects motion in its field of view -- with surprising results.
