Lab 3: Nodal Analysis

Lab 3: Nodal Analysis

Introduction

In this lab, we will analyze, build, and test a circuit containing multiple sources. We will use nodal analysis to predict the circuit behavior prior to building and testing the circuit. We wish to determine the voltage differences V1 and V2. We will then compare the measured circuit response with our expectations based on our analysis.


Procedure

1. Construct the circuit below; measure and record all actual resistance values. Measure the voltages V1 and V2 in the circuit. Calculate a percent error between the measured voltages and your predictions.


2. Take a picture of the completed circuit.


Analysis

1. In the space below, provide a schematic of the circuit, labeled with reference node and values for node voltages as determined in the pre-lab. Provide estimates for the voltages V 1 and V 2 , based on your node voltages.

2. In the space below, provide a schematic of the circuit being testing, including measured resistance values.

3. Provide your measured values for the voltages V 1 and V 2 . Provide a percent error between the measured and expected values of V 1 and V 2 . Comment on any significant differences between the measured and expected values.

Lab 2: Practical Voltage

Lab 2: Practical Voltage and Current Measurement Introduction In this lab  assignment, we will experimentally explore the behavior of non-ideal meters. The experiments in this assignment  illustrate the effects of non-ideal voltage measurements. Procedure 1) Construct the circuit below. Measure the voltage V-out using the DMM. Estimate the internal resistance of the voltmeter. 2) Take a picture of the circuit and include in blog. 3) Repeat the test of part (1), except use the voltmeter on the Analog Discovery module to measure V-out. Estimate the internal resistance of the scope instrument. Analysis 1. Provide the expected output voltage for both ideal and non-ideal voltmeters, based on your pre-lab analysis. 2. Provide a circuit schematic below; include measured resistance values on your schematic. 3. Provide your measured output voltage and your estimated value of the internal resistance of the voltmeter of your DMM. Comment on your results, e...

Lab 1: Solderless Breadboards, Open-circuits and Short-circuits

Lab 1: Solderless Breadboards, Open-circuits and Short-circuits Introduction: The purpose of this lab assignment is to provide users with an introduction to some of the equipment which will be used in subsequent lab assignments. We used breadboards and digital multimeters(DMM) to complete the lab activity. We examine the connections between different holes in a breadboard using a DMM as an ohmmeter. We see which connections correspond to open circuits and short circuits. We also use jumper wires to change the connectivity between holes on the breadboard. Procedure: 1. Using your DMM as an ohmmeter, connect the leads of the DMM to two holes in the same row on your breadboard. DMM measuring 0.5 Ohms. 2. Check the resistance between two rows of holes on opposite sides of the central channel of the breadboard. DMM measuring 1 Mega Ohms. 3. Check the resistance between two arbitrary holes (not in the same row) of your breadboard. DMM measuring 1 Mega Oh...
