In 1971, Leon Chua theoretically proposed the memristor, a fourth fundamental passive circuit element characterized as a nonlinear resistor with memory. Nonlinear circuits have attracted significant interest from physicists and engineers due to their complex behavior and rapidly growing range of applications. The analysis of such systems is often carried out with the help of chaos theory. This study focuses on the Knowm memristor and investigates, through experimental methods, the chaotic behavior of an oscillator that incorporates this nonlinear element. Emphasis is placed on how the system's dynamics evolve with increasing frequency and how it transitions into chaotic behaviors. Fundamental concepts of chaos theory and nonlinear circuit behavior are reviewed, along with the operating principles of the Knowm memristor. Finally, experimental results are presented that confirm the system’s chaotic response and underscore the importance of nonlinear system analysis in modern research and technological development
