Circuits 101

This set of online, interactive, and mobile-friendly labs introduces the basic concepts of analog circuit design normally taught in a first-year Introduction to Electrical Engineering course. For each topic, students will go through a hands-on experience with both simulated and physical components, reinforcing the theory taught in lecture. Built in knowledge checks, just-in-time help features, and note taking capabilities, guide the student through the lab to ensure proper understanding and introductory videos for each topic give relevant real-world background for each topic, answering the question, "when would I use this in the real world?"

In this lab, students will learn how to measure voltage and current using a digital multimeter (DMM). Students will also generate signals using a function generator and measure the signals using an oscilloscope. Finally students will learn how to identify sine, square, and triangular waves and be able to determine the frequency and amplitude of a measured signal
This lab provides an introduction to Ohm's law, an underlying concept for all electrical engineering applications. Students will verify the relationship between current, voltage, and resistance. Students will also learn the basics of circuit simulation in NI Multisim by opening a simulated circuit and using simulation tools to take measurements of a circuit. Lastly, students will learn to reconfigure the components of a circuit schematic to create a different circuit.
This lab introduces Kirchhoff's Voltage Law (KVL) for circuits connected in series. Students will build a simulated series-connected circuit from scratch, demonstrating and verifying KVL in the process.
In this lab, students will explore parallel circuit designs and use Kirchhoff's Current Law to determine the current flowing through each loop of a parallel circuit.
This lab introduces Thevenin's and Norton's Theorem, two theorems that allow us to simplify DC circuit networks, by reducing them to equivalent power supplies and resistances; this allows for a quicker analysis of RL resistance changes. In this lab, students will practice transforming circuits into their Thevenin and Norton equivalents and verify that they are equivalent to the original circuits
This lab introduces the concept of a voltage divider and the whetstone bridge. Students will explore these circuits in simulation and then build them physically to compare their results. Students will be tasked to take the voltage at several points in the circuits and then asked to explain their results with the data they gathered through exploring the circuit.
This lab introduces the concepts of storing electric charge using capacitors. It also goes over the series and parallel configurations of capacitors and how they affect the total capacitance in a circuit.
This lab combines the concepts of resistors and capacitors into one circuit and introduces RC circuits. Students will explore concepts such as the time constant, charging time of the circuit, and how the resistor and capacitor values affect these qualities
This lab introduces the concept of an inductor and second-order circuits Students will explore RLC circuits and determine the resonant frequency of RLC circuits.
This lab introduces the concept power transformation with transformers and how AC voltage can be stepped-up and stepped-down depending on the turn relationships on different legs of the transformer.
