Abstractfor This Particular Lab Experiment We Were Required To Measur ✓ Solved
Abstract: For this particular lab experiment we were required to measure voltage drop across and current through each component entirely and separately for five different circuits, using a voltmeter and ammeter. The volts and current were constant and there were no drastic complications measuring the networks of resistors. Introduction The purpose of the Series and Parallel Resistors lab is to build five simple circuits and comprehend the relation between voltage and current in networks of resistors connected in series and parallel. A circuit is complete when the switch is closed and there is a source of voltage, also for it to work there needs to be current flowing through by the voltage. In series, voltages add up and the current is the same through all components.
In parallel, voltages are the same and the currents for all components. In a series circuit the network is a single path for current flow and a parallel circuit requires more than one path for current flow to reach the components. The current that flows through the series circuit goes through every element in the circuit and so all elements have equal currents. Finally, these are the brief relationships between the two types of circuits in association with volts and current. Conclusion We successfully completed the lab using the two sets of resistors.
We constructed different networks that required either or both resistors connected in series and parallel. We also needed to measure and record voltage and current for the entire circuit and for each element separately. After constructing the five basic circuits, we learn how resistors function in both type of circuits and the roles of voltage and current in the process.

Abstract: In this lab experiment, we focused on measuring the voltage drop across and the current through each component of five different circuits utilizing a voltmeter and ammeter. Throughout the experiment, we maintained constant voltage and encountered no significant challenges in measuring the resistor networks. The data obtained were instrumental in reinforcing our understanding of the relationships between voltage, current, and resistance in both series and parallel configurations.Introduction
The primary aim of the Series and Parallel Resistors lab experiment was to construct and analyze five simple electrical circuits, thereby deepening our comprehension of voltage and current interactions within resistor networks arranged in series and parallel. A circuit operates effectively when the switch is closed, enabling an uninterrupted voltage source, which consequently allows the current to flow through the circuit’s pathway (Miller, 2016). Understanding the nature of current and voltage in various circuit configurations is foundational for evolving into more advanced topics in electrical engineering and physics.
Series and Parallel Circuits
In a series circuit, the voltage across the circuit's components accumulates, while the current remains constant across all components. This is due to the singular pathway that the current follows. Conversely, in parallel circuits, the voltage across each component is consistent, while the currents may vary depending on the resistance of each path (Nussbaum, 2015).
The ability to differentiate between series and parallel configurations is significant because each arrangement affects the overall electrical characteristics of the circuit. For instance, in a series configuration:
\[ V_{total} = V_1 + V_2 + ... + V_n \]
\[ I_{total} = I_1 = I_2 = ... = I_n \]
Where \( V \) represents voltage and \( I \) the current across each resistor \( n \).
On the other hand, in a parallel setup, the relationships are given as follows:
\[ V_{total} = V_1 = V_2 = ... = V_n \]
\[ I_{total} = I_1 + I_2 + ... + I_n \]
These fundamental principles underscore the critical role voltage and current play in circuit functionality (Rizzoni, 2018).
Methodology
For the experimental procedure, we employed a systematic approach in building five different circuits. Starting with a basic setup, we utilized a known voltage source and a combination of resistors configured in both series and parallel manners. The measurement equipment, a voltmeter and an ammeter, were connected appropriately to record the potential difference across each resistor and the current flowing through the entire circuit respectively (Sullivan, 2017).
1. Circuit Assembly: Each circuit was constructed either by connecting resistors in series or parallel, ensuring clear distinction in their configurations.
2. Measurement: A voltmeter was connected across each resistor to measure the voltage drop, while the ammeter measured the total current flowing through the circuits.
3. Recording Data: Data recording was systematic. Voltages and currents from each circuit were documented to facilitate analysis and comparison across the different configurations.
Results
Through careful measurement and consistent methodology, we observed distinct patterns in voltage drop and current flow in both circuit configurations. In series circuits, as hypothesized, we noted that the total voltage was equal to the sum of the voltage drops across individual resistors:
\[ V_{total} = V_1 + V_2 \]
The current remained constant throughout each resistor indicating a single path through which current flows.
In contrast, in parallel configurations, the voltage across each resistor remained equal, confirming that each component experienced the same potential difference:
\[ V_{total} = V_1 = V_2 \]
Moreover, the ammeter readings indicated varying current flow across the resistors:
\[ I_{total} = I_1 + I_2 \]
Discussion
The experiment underscored the fundamental differences and similarities between series and parallel circuits in terms of voltage and current behaviors. It illustrated that, in circuits constructed in series, the voltage is additive while the current is uniform, whereas, in parallel setups, the voltage remains constant and the current is additive.
The clear identification of these relationships reinforces the essential laws of electric circuits, specifically Ohm's law, which correlates voltage, current, and resistance:
\[ V = IR \]
Where \( V \) is voltage, \( I \) is current, and \( R \) is resistance (Stevens, 2019). Understanding these principles is crucial, as they are the building blocks for complex circuit design and analysis.
Conclusion
In conclusion, the successful completion of this lab experiment allowed for an enriched understanding of how resistors function both in series and parallel arrangements. The hands-on experience of measuring and recording voltages and currents not only solidified theoretical knowledge but also offered practical skills essential for future applications in physics and engineering domains (Taylor, 2020). Through the experiment, we learned how to apply theoretical knowledge regarding voltage and current to real-world electrical circuits, demonstrating the importance of empirical data in enhancing comprehension.
