A carbon film resistor is one of the most widely used fixed resistors in electronic circuits. It belongs to the carbon-based resistor family, where resistance is obtained from a thin layer of carbon deposited on an insulating substrate. Due to its moderate cost, good stability, reasonable accuracy, and wide resistance range, the carbon film resistor […]

Passive RC Filters: Circuit Diagram, Types, Working and Applications
RC filters are the most fundamental signal-processing circuits in electronics. It uses a combination of a resistor (R) and a capacitor (C) to selectively allow or suppress signals based on their frequency. Despite its simplicity, the RC filter plays a crucial role in almost every electronic system, from basic audio amplifiers to complex communication and […]
Difference Between Photodiode, Phototransistor and Photoresistor
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 […]
