ECEN 301 Student ____________________________ Sec ____ Electrical Engineering for Engineers Brigham Young University Lab 3: Kirchhoff’s Laws and Equivalent Circuits TA Pass-off (4 pts) Objectives Demonstrate the ability to solve for voltages and currents in circuits with multiple branches using Mesh-current and Node-voltage analysis methods. Learn how to practically determine circuit equivalents using Kirchhoff’s laws. Pre-lab Work Please do the pre-lab work before you come to lab . You will then be able to begin the lab work immediately and get meaningful help from the instructors. 1. Review the Mesh-Current and Node-Voltage methods for solving circuits. 2. You could use Thèvenin equivalents, series and parallel equivalent resistances, and voltage and current dividers to solve the whole circuit, but we will use the Mesh and Node methods in this lab. For the circuit shown below calculate the Mesh Current in each loop. For this lab, treat the LED as a constant voltage source equal to your Lab2 value (or ~2V), where the positive terminal is connected to node a . 301_Lab03 21 Jul 2005 dad Page 1 of 8 + R 1 = 82 Ω R 2 = 330 Ω LED 150 Ω = R 3 33 Ω = R 4 R 5 = 56 Ω R 6 = 68 Ω 120 Ω = R 7 10 V i 1 i 2 i 3 i 4 i 5 i 6 R 8 = 100 Ω a b c d

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
