How does a Filter capacitor work? Basic principles of a capacitor To understand the working of a filter capacitor, let’s first discuss the basic principles of a capacitor. A capacitor is a passive electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated […]

Introduction to Transformerless Power Supply A transformerless power supply is a type of power supply that does not use a transformer to step down or step up the voltage. Instead, it relies on other components such as capacitors, diodes, and resistors to convert the AC mains voltage to the desired […]

Introduction to Audio Amplification Audio amplification is the process of increasing the power of an audio signal to drive speakers or headphones. It is a crucial component in any audio system, whether it’s a home theater, car stereo, or portable music player. The LM1875 is a popular choice for audio […]

What is a Rectifier? A rectifier is an electrical device that converts alternating current (AC) to direct current (DC). It allows current to flow in only one direction, blocking the reverse flow. Rectifiers are commonly used in power supplies to provide the necessary DC voltage for electronic circuits and devices. […]
