In the previous tutorial, we learned about signal behavior and the role of a capacitor in a circuit. A capacitor stores electrical charge in the form of the electrostatic field in response to an applied voltage. It charges whenever the applied voltage increases (relative to the current-voltage across the capacitor) by allowing a charging current…

Electronic gadgets have transformed how we learn and teach, revolutionizing many aspects of education. Thanks to advancements in technology, remote learning is now accessible to anyone, anywhere, meaning it’s possible to learn from educators globally without leaving home. Internet-powered devices and artificial intelligence have made personalized, data-driven education a reality, which increases engagement through customized…

We have already discussed fixed resistors and variable resistors. Interestingly, resistors are not just limited to be used for limiting current, dropping voltage and dissipating power. There are many special types of resistors which work as transducers too and so, they can be used as sensors in the circuits. A transducer is a  device which…

In a previous article, we discussed various types of fixed resistors, selection of resistor type for a given circuit, and identifying value, tolerance and power rating of fixed resistors. Let’s now talk about variable resistors. The resistance of variable resistors can be adjusted manually or digitally. The variable resistors offer a range of resistance instead…

In the previous article, we presented a resistor selection reference table. With the help of this table, you can determine which type of resistor will be most suitable for a given circuit or application. Once you’ve determined which type of resistor suits the best, it’s time to pick up the desired resistor. For that, it…

Digital circuit design is a critical part of electronics. In fact, most electronic components are digital electronic circuits. Even simple integrated circuits (ICs) contain thousands or hundreds of thousands of transistors. Microprocessors and microcontroller ICs typically have millions or billions of transistors. Most ICs are produced in fabs, but digital circuit designs can be made…

A major challenge in electronic circuit design is selecting suitable components that perform well under all operating conditions. This is particularly essential in regards to the safe operating limits of current, voltage, power, and temperature.  Here, we’ll focus on temperature. Every electronic component generates heat while transferring power. Bear in mind there are no perfect…
