FLORIDA INTERNATIONAL UNIVERSITY COLLEGE OF ENGINEERING AND COMPUTING DEPARTMENT OF ELECTRICAL AND COMPUTER ENGINEERING EEL 3110C LABORATORY COMPONENT SECOND ACTIVITY: Verifying Kirchhoff’s Voltage Law and Kirchhoff’s Current Law. 1- Set Up the following circuit. Verify Kirchhoff’s voltage and current laws. Measure and tabulate all currents and voltages. Briefly explain and comment your results. Theory and Purpose The purpose of the lab and this circuit in general is to challenge and reinforce our knowledge and understanding of Kirchhoff laws for calculating current and voltage. This circuit in particular will put our knowledge to the test regarding the addition of resistors in parallel and in series. In this circuit It is important to consider that the resistors are in parallel, which mean we have to use another formula to add them.
Rtotal= 1/R1 + 1/R2 + 1/Rn... . Once we find the total resistance, we proceed to use ohm’s law to solve the rest of the circuit. Results Current: IR1 =2.5mA, IR2 =0mA, IR3 =2.5mA, IR4 =2.5mA, IR5 =2.5mA Voltage: VR1 =2.5V, VR2 =0V, VR3 =2.5V, VR4 =2.5V, VR5 =2.5V Handwritten results

Discussion and Analysis Most of the difficulties of this circuits came from setting up the actual circuit on the breadboard. Through some trial and error, and looking at difference sources, realized how to set up the circuit in the easiest configuration possible and how to manipulate the resistors and cables to get it to work. For this circuit, we had to once again go over Ohm’s law( V= I x R) and Kirchhoff’s voltage law and Kirchhoff’s Current law. It was also the first time I had to use nodal method. Conclusion Statement: As stated before, this lab reinforces our knowledge of Kirchhoff’s laws of voltage and current as well as Ohm’s law and the nodal method. This time was slightly more difficult due to the numbers of resistors we had to add whether it was in series or in parallel. Once I was able to set it up on the breadboard and simulate on multisim it became much easier to comprehend. While some of the answers and calculations were slightly off with a reasonable margin of error, the numbers and answers matched. In conclusion, this lab proved to be useful in understanding Kirchhoff laws.
