In this article we study how potentiometers work and try to understand how to connect potentiometers in electronic circuits. How Potentiometers Work Potentiometers, or pots as these are called in short form are passive electronic devices which are basically just variable resistors, or resistors whose values can be altered from zero maximum within the given […]

Difference Between Current and Voltage – What is Voltage, What is Current
The following data explains the important aspects connected with the electrical parameters like voltage and current, the content also explains in simple words how to differentiate the two parameters. What is Current It is the number of electrons flowing at any instant through a conductor or across the positive and the negative of a conductor […]
Basics of Strain Gauge Measurements
The strain gauge is one of the most useful tools for precisely measuring expansion or contraction of a material as forces are applied. Strain gauges are also useful for measuring applied forces indirectly if they are aligned approximately linearly with the deformation of the material. What are Strain Gauges Strain gauges are sensors whose electrical […]
How Mosquito Traps Work
Mosquito and other forms of fly trap mechanisms work by making use of luring techniques for attracting the insects, which involve carbon dioxide gas, body odor simulators and ultraviolet lights. These traps become very useful in areas which may be highly infested with mosquitoes, however due to its high costs such traps are not very […]
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 […]
Transistor Stray pickup False Triggering Problem
In this article I have explained how to make any BJT or mosfet based circuit free from stray signal pickup and false triggering by simply attaching a filter resistor or a capacitor across their base/emitter or gate/source terminals. The problem was raised by Mr.Henrik. Solving a Circuit Problem I have an issue I don’t understand. […]
