Daytona State CollegeEET3085L Electricity and Electronics Lab 1 Lab session No: 5 Date: February 23 rd 2021 Topic: Parallel dc Circuits Experiments : 7 (Parallel dc Circuits) Objectives: 1. Become familiar with the Kirchhoff current Law. 2. Learn how to measure currents and voltages and determine the value of currents in parallel circuits. 3. Learn how to apply current divider rule in parallel circuit respectively. Pre-lab Assignments: 1. Read chapters 6 (Parallel dc Circuits) 2. Watch lectures 4, 5 and 6. 3. Read the Résumé of Theory for the lab document in Parallel DC. 4. Proceed with the preparatory questions given below. Answer the following questions: 1. Calculate the equivalent total resistance of the following circuit of figure 7.3: 2. Using Kirchhoff current law, calculate each one of the currents :I s , I 1 and I 2 of the circuit in figure 7.4. 3. Usign Multisim verify the results of question 2.
Daytona State CollegeEET3085L Electricity and Electronics Lab 2 Procedure Complete each one of the experiments from the document Experiment 7: Parallel DC Circuits. Use the values given in the procedure as measured values. Verify the results with Multisim. Part 1 Basic Measurements a) Assumed values for R 1 and R 2 : R 1measured = 1.24 kΩ R 2measured = 3.18 kΩ b) R T measured = 0.89 kΩ e) Measured values for V R1 a nd V R2 . V R1measured = 12 V V R2 measured = 12 V g) Measured currents for circuit in figure 7.4 I 1measured = 9.75 mA I 2measured = 3.78 mA I 3 measured = 13.5 mA Use Multisim to verify all measured values in parts e) and g) . Part 2 Equal Parallel Resistors a) For figure 7.5 R 1measured = 2.23 kΩ R 2measured = 2.24 kΩ c) R ohmeter = 1.11 kΩ g) Measured currents I 1measured = 5.4 mA I 2 measured = 5.36 mA
