RC Time Constant Investigation using Arduino and a Simple Circuit-based Approach

Abstract

The RC time constant is a measurement of the rate at which a capacitor charges or discharges in an electrical circuit via a resistor. This property is useful in a wide range of applications, including signal processing, power supply, and so on. The purpose of this study is to analyze the RC time constant using an Arduino as well as a simple circuit-based approach. We utilized an Arduino-based approach to clock the time it takes a capacitor to charge through a resistor and then compared the findings to theoretical expectations. We constructed a basic circuit with a capacitor and a resistor for the simple circuit approach. Examine the charge curve data using voltage and time measurements. This research has shed light on the behaviour of the RC time constant and showed the benefits and drawbacks of different configurations.
