Resistors, Electromotive Force and Power Dissipation
https://www.electronics-lab.com/article/resistors-electromotive-force-and-power-dissipation/
Resistors A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. It is a conductor that impedes the flow of electric charge through it, creating electrical resistance. Such resistance results from collisions between free electrons and the crystal lattice of the conductor’s atoms. This is the main property of resistors. […]

Isabellenhütte introduces new range of 1 – 6mΩ resistors in smallest chip sizes available on the market
https://www.electronics-lab.com/isabellenhutte-introduces-new-range-1-6m%cf%89-resistors-smallest-chip-sizes-available-market/
Isabellenhütte has developed a new range of precision resistors in standard sizes with resistances ranging from 1 to 6 mOhm for applications which require small and low-ohmic shunts. In terms of their construction, the components are also less complex than the current ISA-PLAN®resistance families. And yet, they offer the same performance quality: very good long-term […]

This video describes and demonstrates the 4-wire resistance measurement (Kelvin connection) – what it is, and when & why it is used for making low valued resistance measurements. 4 Wire Resistance Measurement – Kelvin connection – [Link]
Analogue Sensors – Calculate the Nonlinearity Introduced by a Load or Pull Down Resistor
https://www.electronics-lab.com/analogue-sensors-calculate-nonlinearity-introduced-load-pull-resistor/
Tecwyn Twmffat @ instructables.com discuss about the notlinearity introduced by adding a pull down resistor and why you may get unpredictable readings from your ADC. For many years I found that I would get strange, unpredictable, readings from my sensor related projects at the maximum and minimum locations when using analogue digital convertors (ADCs). I […]

In this guide Sanket Gupta @ octopart.com explains how to select a resistor from a range of common resistor types. In this blog, we will explain all the different types of resistors, their merits and demerits, and popular applications. We have included some recommendations for commonly used resistor series with high supply chain availability from the Common […]
Precision programmable current source uses two ICs
https://www.electronics-lab.com/precision-programmable-current-source-uses-two-ics/
by Stefano Salvatori & Pietro Oliva @ edn.com: This Design Idea mates a precision current source IC with precision difference amp chips to create a programmable current source or sink. The resistor-programmable current source/sink in Figure 1 illustrates the basic topology, taking advantage of tightly matched on-chip resistor ratios instead of relying on absolute tolerances. Precision programmable […]
