Introduction

The objective of this experiment was to analyze and understand the behavior of electrical circuits, specifically focusing on how the addition of components such as light bulbs in series and parallel configurations influences current and voltage across each component. By comparing measured values with theoretical predictions, the goal was to validate fundamental principles of electrical circuit theory and identify potential factors influencing the accuracy of experimental results.

Theoretical Background

Ohm's Law states that the current passing through a resistor is directly proportional to the voltage across it, with resistance being the proportionality constant. In series circuits, the total resistance is the sum of individual resistances, leading to a decrease in overall current as more bulbs (resistive elements) are added. Conversely, the voltage is divided among the bulbs proportionally, resulting in a decrease in voltage across each bulb with additional bulbs. In parallel circuits, the voltage across each component remains constant, while the total current increases with additional bulbs, as each bulb offers an independent path for current. As the number of bulbs increases in parallel, the overall resistance decreases, leading to an increase in total current.

Methodology and Data Collection

The experiment involved setting up series and parallel circuits with light bulbs, measuring the current and voltage across each bulb, and recording the data. Predicted values were calculated based on theoretical principles, and these were compared with measured data. Excel tables were created to organize the results, including columns for predicted values, measured values, and uncertainties.

Analysis

The comparison of predicted and measured values revealed that most measurements fell within the anticipated error margins, affirming the reliability of theoretical models. When discrepancies appeared beyond the error margins, potential causes such as variations in bulb resistance, contact resistance, or measurement instrument calibration were considered. It was observed that in series circuits, adding more bulbs decreased the current and voltage per bulb, consistent with expectations. In parallel circuits, increasing bulbs raised the total current while maintaining the voltage across each bulb.

Discussion and Conclusion

The results demonstrated conformity with theoretical expectations, illustrating fundamental electrical principles. In series configurations, additional bulbs resulted in reduced current and voltage per bulb, confirming Ohm's Law predictions. In parallel configurations, the constant voltage across each bulb and the increase in total current with more bulbs aligned with theoretical models.

This experiment underscores the importance of circuit configuration in influencing electrical behavior. Practical factors such as internal resistance and contact resistance can impact measurements, but these deviations were accounted for within the experimental uncertainties. Overall, the experiment enhanced understanding of circuit theory, highlighting the practical implications of adding resistive elements in different circuit configurations.
