linear potentiometer
A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.
Linear potentiometers have unique features to ensure long trouble-free life in the harshest of environments from motorsport to structural monitoring, from measuring linear position or displacement in a wide variety and broad range of manufacturing and process equipment.
Series and parallel circuits
Two-terminal components and electrical networks can be connected in series or parallel. The resulting electrical network will have two terminals and can participate in a series or parallel topology. Whether a two-terminal "object" is an electrical component or an electrical network is a matter of perspective. This article will use "component" to refer to a two-terminal "object" that participates in the series/parallel networks. But what are the differences between series and parallel circuits?
Series and Parallel Circuit_ Close circuits have a complete path for current to flow in a loop. An open circuit does not have a closed-loop, which means that it’s not operative. A short circuit is a low-resistance path, usually made accidentally, that bypasses some parts of a circuit. A short circuit can occur when two bare wires in a circuit meet each other. Read more
Forward Bias vs. Reverse Bias
In forward bias, the positive terminal of the battery is connected to the p-type material and the negative terminal is connected to the n-type material so that holes are injected into the p-type material and electrons into the n-type material. The electrons in the n-type material are called majority carriers on that side, but electrons that make it to the p-type side are called minority carriers.
In reversed bias, there is a connection between the negative region and the positive terminal of the battery, and the positive region is joined to the negative terminal. The reverse potential boosts the strength of the potential barrier in this situation.
