I did a physics lab and got some values. I want to check them theoretically to see how the results differ. From this diagram, answer the following questions: The laws to be verified included the conservation of current in a node, the addition of potentials for components in series, and the addition of currents for components in parallel. The data : R1: 1094 ohm R2 : 998 ohm R3: 1094 ohmR4: 25 ohm Source 1 : 5 V Source 2 : 1.5 V

Lrocedure A- Kirchhoff's voltage law: The circuit in Figure 2 will be used o test the valdity of Kirchhoffs voltage law, Figure (2) Construct the circuit as shown in the figure (2). Measure the power supply output voltage and the potential drops across each of the thrae resistors. Record these measurements in your lab notebook as in the following table: University of Ti-Qar/ Departmnt of Elctricl aad Fectronlc Enginearing / Prepared by M 5¢ Al Karvem Soes 1+ Stage: Fundamentals of Flectrical Engineering | Lob 3 - Kirchhoff's Laws. 201520, Table 1; data collected for testing the validity of Kirchhot?s voltage law. 3)From your experimental data (table 2), calculate the total current into the node point P. Now calculate the total current out of the node point P along with its uncertainty. Does the current into the node agree with the current out of the node within experimental uncertainty?
