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 […]

Light Dependent Resistor (LDR) / Photoresistor Circuit Diagram & Working
Light Dependent Resistor (LDR) are widely used in various applications where light detection is required, such as in automatic street-lights, camera light meters, and burglar alarm systems. This article will delve into the symbol, construction, working principle, characteristics, advantages, disadvantages, and applications of LDRs. Additionally, a simple LDR circuit to detect light will be explained […]
What are Potentiometers or Variable Resistors
Potentiometers are electrical component used to measure or adjust voltage or current, it usually consists of a rotary or sliding adjusting device, and three electrical contacts, one of which is connected to the power supply, the other is grounded, and the third can be moved on the adjusting device of the potentiometer, which can be […]
