# Labs for Analog and Digital Courses using NI ELVIS II and NI Multisim

This comprehensive laboratory set for analog and digital curriculum was developed by educators to teach DC circuits, AC circuits, analog electronics, and digital electronics. Each lab comes complete with detailed instructions, NI Multisim circuit files, and NI ELVIS setup descriptions. Two key labs also include virtual instruments developed in LabVIEW. The NI ELVIS and Multisim platform combine to provide students with a strong foundation of electrical engineering concepts through simulation and hands-on circuit building.

### LEARNING OBJECTIVES

• Students learn the fundamental concepts of DC circuits, AC circuits, analog electronics, and digital electronics all the way from Ohm's Law to Analog-to-Digital converters.
• Students are guided through experiments that are reinforced through hands-on circuitry building with the NI ELVIS and computer simulation of Multisim.

### INCLUDED COURSE LABS

Students verify the three ways in which Ohm's law can be used to calculate voltage, current and resistance.
Students verify that the total resistance of a circuit in series is the individual sum of the resistors and check Kirchhoff's voltage law for circuits connected in series.
Students recognize the features of parallel resistive circuits and check Kirchhoff's current law for various circuits.
Students create and simulate Thevenin and Norton equivalent circuits using NI ELVIS and Multisim.
Students learn the operation of a voltage divider and the behavior of a resistance bridge through the NI ELVIS multimeter.
Students verify the capacitance behavior of capacitors connected in series and in parallel.
Students learn the principle of operation of an RC circuit and observe a capacitor's charge and discharge curves.
