If you have understood correctly, how to use transistors in circuits, you might have already conquered half of electronics and its principles. In this post we make an effort in this direction. Introduction Transistors are 3 terminal semiconductor devices which is able to conduct relatively high power across their two terminals, in response to a […]

How to Switch Two Batteries Manually using Opto Coupler
The following article explaining a dual battery changeover relay circuit was requested by Mr.Raja so that it could become possible to switch between his old and new inverter batteries automatically, eliminating manual interventions. Let’s read it in details. Technical Specifications “I bought a new 12v 110 Ah lead acid battery for the dc home lighting system. I had another 12v […]
How to Compare IGBTs with MOSFETs
In this post I have explained the main differences between an IGBT and a MOSFeT device. I have explained more about the facts from the following article. Comparing IGTB with power MOSFETs The insulated-gate bipolar transistor features a voltage drop which is significantly low when compared to a conventional MOSFET in the devices which have […]
How to Connect Diodes in Parallel
In this post we systematically discuss how to connect diodes in parallel for getting upgrading the overall current specifications of the assembly. This requires special circuit arrangement to ensure uniform current distribution between the devices. Whenever an inductor based load is involved in a DC circuit, incorporating a back EMF protection diode or a freewheeling […]
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 to Identify Component Specifications in Schematics
In this post I have explained the correct way of understanding and identifying component specifications in a given circuit schematics, even if the details are missing in the document or the schematic. Schematics without Part Specifications When a new hobbyist searches for a particular electronic circuit of his choice, the internet provides him with a […]
