Hacks of Electronics
In the field of electronics and optoelectronics, light-sensitive devices play a crucial role in converting light signals into electrical signals. Among the most widely used light sensors are the Photodiode, Phototransistor, and Photoresistor (also known as Light Dependent Resistor or LDR). Though they all respond to light, their construction, working principles, advantages, disadvantages, and applications […]
Introduction: In electronic circuit design or repair, selecting the right capacitor is critical to performance and reliability. Ceramic and electrolytic capacitors are two of the most commonly used capacitor types, each suited for distinct applications due to their differing structures and electrical characteristics. Understanding their key differences – including capacitance range, frequency response, polarity requirements, […]
Let’s Explorer Carbon Composition Resistor symbol, construction, working, types, value reading, advantages, disadvantages, and applications explained in the clearest way. Carbon composition resistors were once the most common type of resistors used in electronic circuits. Though largely replaced by more modern resistor types today, they still hold importance in high-energy pulse and vintage circuit applications. […]
Resistors are fundamental electronic components that limit, regulate, or set the flow of electric current in a circuit. While they may appear simple, there are different types of resistors designed for specific purposes and operating environments. Now you know the basics of resistance and its role in circuits. Let’s dive deeper into the all the […]
