Adamczyk Section 01 February 22, 2005 Lab Report #1 By Dan Schwarz 2 Abstract This paper describes an experimental procedure that was used to demonstrate the validity of Kirchhoff’s Current Law, Kirchhoff’s Voltage Law and Ohm’s Law. The procedure implemented a simple circuit constructed of resistors. Current and voltage measurements were taken from the circuit and compared to Kirchhoff’s current and voltage laws in order to prove them. After confirming Kirchhoff’s Current Law and Kirchhoff’s Voltage Law, the voltage and current measurements taken during the procedure were used to confirm Ohm’s Law. 1.0 Introduction Kirchhoff’s voltage and current laws in combination with Ohm’s Law are the fundamental tools of circuit analysis and as such must be investigated. Kirchhoff’s Current Law states that the sum of the currents entering a node must be equivalent to the sum of the currents leaving that node. To verify this law, measurements were taken of the current at every path that was connected to a node. Kirchhoff’s voltage law states that the sum of the voltages in any given loop of interconnected elements must be equal to zero. To verify KVL, measurements were taken across each resistive element in one loop to determine whether the loop would adhere to KVL. Ohm’s Law states that the voltage across any element is equal to the product of current and resistance. Since the current through each element and the voltage across each element was measured, Ohm’s Law could be implemented to calculate each element’s resistance. Ohm’s Law was verified by comparing the nominal resistance values to the values calculated using Ohm’s Law. 3 This paper explains the fundamental circuit laws and outlines the procedure used to prove those laws. Sections 2.02.3 discuss the significance of KCL, KVL and Ohm’s Law and offer formal definitions for each. Sections 3.03.2 demonstrate how the resistive circuit was used to prove the fundamental circuit laws. Lastly, Sections 4.04.2 offer a detailed description of the experimental procedure conducted on the circuit. 2.0 Fundamental Circuit Laws To obtain a full appreciation of the significance of Kirchhoff’s Voltage Law, Kirchhoff’s Current Law, and Ohm’s Law, one must understand their applications to circuit analysis. KVL can be used to evaluate a loop of interconnected elements within a circuit. can be used to evaluate a loop of interconnected elements within a circuit....
