In this experiment, we aimed to demonstrate and validate Ohm's Law (V = I * R) and Kirchhoff's Laws, including Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL). These laws are fundamental principles in electrical circuits, and this lab utilized a multimeter to measure current and voltage in both series and parallel circuits to test their applicability. Despite encountering some challenges with equipment and measurements, the results supported the hypothesis that Ohm's and Kirchhoff's Laws can be reliably used in electrical circuits.
Ohm's Law (V = I * R) is a fundamental equation in electrical engineering, describing the relationship between voltage (V), current (I), and resistance (R) in an electrical circuit. Kirchhoff's Laws, introduced by German physicist Gustav Kirchhoff, consist of Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL). KVL states that the sum of voltage rises and drops around any closed loop in a circuit must be equal. KCL asserts that the total current entering a junction in a circuit must equal the total current leaving the junction.
These laws serve as foundational principles for analyzing and understanding electrical circuits. To validate and apply these laws, we conducted experiments using a multimeter to measure current and voltage in both series and parallel circuits.
The following materials were used in the experiment:
g., 3V, 4.5V, 6V, 7.5V).
The experiment proceeded systematically, although we encountered challenges along the way. Initially, we had difficulties with the multimeter, which was not providing accurate readings due to incorrect settings. Once resolved, we conducted experiments to validate Ohm's Law and Kirchhoff's Laws.
Regarding Ohm's Law, we measured current in a series circuit with different voltage levels. The results generally supported the hypothesis that the relationship between voltage, current, and resistance adheres to Ohm's Law. However, discrepancies in readings were observed, likely attributed to the quality and condition of the power supply and resistors, as well as rounding errors in calculations.
For Kirchhoff's Voltage Law, we examined voltage drops across resistors in parallel circuits. While the theory was upheld, we also encountered minor discrepancies in voltage readings, which could be attributed to the same factors as in the Ohm's Law experiment. Nevertheless, the overall trend supported KVL.
In the case of Kirchhoff's Current Law, constructing and validating the circuit proved more challenging. The complexities of the circuit and our understanding of its configuration caused delays. Eventually, we confirmed KCL by verifying that the current entering a junction equaled the current leaving the junctions. This aspect of the experiment was instrumental in reinforcing Kirchhoff's Laws.
In conclusion, our results generally supported the hypothesis that Ohm's and Kirchhoff's Laws are reliable principles for analyzing electrical circuits. Although variations in readings occurred, several factors contributed to these discrepancies, including equipment quality and rounding errors. Despite these challenges, the experiment provided valuable insights into the practical application of these fundamental laws.
The experiment aimed to validate Ohm's Law and Kirchhoff's Laws (KVL and KCL) using a multimeter to measure current and voltage in series and parallel circuits.
