Resistors may look small, but they play a critical role in keeping electronics safe and functional. This video explains what ...

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 series ...

Find a downloadable version of this story in pdf format at the end of the story. Motors are used in countless consumer electronics applications, and technology improvements that have led to more ...

The 4-20 mA transmitters used in industrial current-control loops can be implemented as powered current sources, remote non-powered current sinks, or with several other I/O combinations. A useful ...

With so much analog-circuit design being done by automated tools and circuit-performance analysis done with tools such as Spice, it may seem anachronistic to actually go through a basic circuit in ...
