In this post I have explained some important current mirror circuits, and how to design practical circuits using current mirror concepts. Current Mirror Definition A current mirror is a circuit that copies a current through one active device by regulating the current in another active device in the circuit, maintaining a constant output current independent […]

How to Select MOV – Explained with a Practical Design
MOVs or metal oxide varistors are devices designed for controlling mains switch ON surges in electrical and electronic circuits. Selecting an MOV for a particular electronic circuit might require some consideration and calculation, I have explained the procedures here. What are MOVs Metal oxide varistors or simply varistors are non-linear surge suppressor devices which are […]
Understanding Color Codes of Resistors with Practical Examples
In this post I will comprehensively explain regarding the various standard resistor color codes, and systems employed for assigning resistors their specific values. The post also explains how to read and identify resistor values from their color codes. By: S. Prakash The color codes used in resistors denote a leaded resistor’s value. These color codes […]
How Flex Resistors Work and how to Interface it with Arduino for Practical Implementation
As electronics enthusiasts we may come across many kinds of resistors, from small fixed resistor to high current bulk rheostat. There are humongous classifications among resistors, but here we will focus on a particular kind of resistor called “flex resistor” and learn how it works. As the name signifies a flex resistor is flexible and […]
CREE XM-L T6 LED Driver Circuit – Specifications and Practical Application
This article explains how to illuminate a Cree XM-L T6 LED using a current controlled driver circuit while the supply input is from a battery, or in case a mains SMPS is intended as the driver unit. The idea was requested by Mr. Jaco. Technical Specifications Thanks for the great advice and circuits! Have you […]
