In the previous article I explained about ripple factor in power supply circuits, here we continue and evaluate the formula for calculating ripple current, and consequently the filter capacitor value for eliminating the ripple content in the DC output. The previous post explained how a DC content after rectification may carry the maximum possible amount […]

How to Design a Buck Converter Circuit: Formulas and Calculations
In this post I have explained the method of designing buck converter circuits by calculating all the required parameters, in order to ensure an optimal performance from these devices. We take the example of IC 555 buck converter typologies, and try to understand the optimizing techniques through equations and manual adjustments, for achieving the most […]
How a Connect a Potentiometer
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 […]
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 […]
