The purpose of this experiment was to investigate the relationship between voltage, current, and resistance in an electrical circuit, a fundamental concept in physics and electrical engineering. Understanding this relationship is crucial for designing and analyzing electrical systems, and it is governed by Ohm’s Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across those points and inversely proportional to the resistance. Mathematically, Ohm’s Law is expressed as V = IR, where V is the voltage, I is the current, and R is the resistance.

The rationale for conducting this experiment stems from the need to empirically verify the theoretical principles of Ohm’s Law and to observe how various resistors influence circuit behavior. By measuring current and voltage across different resistors, we can confirm the linear relationship posited by the theory. Accurate measurements require the use of a voltmeter and an ammeter, with careful attention to circuit connections and potential sources of error such as contact resistance or instrument calibration issues.

In the experiment, a circuit was constructed with a power supply, resistors of known resistance, a voltmeter, and an ammeter. The voltage across the resistor and the current through it were measured for several resistor values. These measurements were then used to calculate theoretical currents and compare them with the actual readings obtained from the ammeter. The results confirmed the direct proportionality between voltage and current and demonstrated that the experimental data aligned closely with the predictions of Ohm’s Law.

The experimental findings reinforced the fundamental concept that resistance remains constant over the range of voltages applied, validating the linear relationship between current and voltage. Minor deviations observed in the measurements could be attributed to contact resistance, meter accuracy, or temperature variations affecting resistor resistance. Overall, the experiment successfully illustrated the application of Ohm’s Law and provided practical insight into circuit analysis.

In conclusion, the experiment demonstrated that electrical current varies proportionally with voltage, confirming the validity of Ohm’s Law within the conditions tested. Understanding this relationship is essential for electrical circuit design and troubleshooting. The outcomes highlighted the importance of precise measurement techniques and awareness of potential error sources to accurately interpret results and apply fundamental electrical principles in real-world contexts.
