Linear Circuit

A linear circuit is an electrical system where the relationship between voltage and current follows a straight-line pattern, meaning that if you double the input, the output also doubles. Components like resistors, capacitors, and inductors in a linear circuit behave predictably, making the overall behavior easier to analyze and predict. These circuits adhere to principles like superposition and proportionality, allowing engineers to simplify complex problems by breaking them into manageable parts. In essence, linear circuits provide a predictable, straightforward framework for controlling and understanding electrical signals.
