Ohm’s Law and Kirchhoff’s Law

The purpose of the first lab experiment is to determine the relationship between current and voltage in a circuit. The experiment is conducted to check whether the current passing through between two points is directly proportional to the potential difference or voltage across the two points when the resistance is kept constant. In this experiment, voltage was gradually increased to observe the corresponding changes in current. Results indicate that as voltage increases, current also increases and vice versa, confirming a direct relationship when resistance remains constant. Additionally, the second part of the experiment focused on verifying Kirchhoff’s Current Law (KCL) and Kirchhoff’s Voltage Law (KVL). It was observed that in a parallel circuit, both current and voltage remain constant throughout. The division of current in parallel circuits and the verification of voltage conservation through KVL were also demonstrated. Thus, this lab successfully verified Ohm’s Law and the principles underlying Kirchhoff’s Laws, highlighting that current remains constant in series circuits while it divides in parallel circuits. Overall, the obtained results were satisfactory and consistent with theoretical expectations.
