Basic Power supply circuits Part 1

To understand power supply circuits, we need to understand rectifiers. A rectifier converts AC or alternating current to DC direct current. Rectifiers are used in Power supply circuits which we will discuss in detail. The process of converting AC to…

Introduction Electronic component can be divided into 2 types: Active and Passive components Resistors and Capacitors etc. are known as passive components because they can only attenuate the electrical voltage and signals and cannot amplify. Devices like transistors and operational amplifier(op…
