Voltage Dividers and Resistance Bridges

In this lab, students will learn how to recognize and analyze voltage divider and resistance bridge circuits. A voltage divider is a linear circuit that produces an output voltage smaller than its input voltage; it works by splitting the input voltage among its components. A bridge circuit is a circuit with two branches that are connected by a conductive bridge. Both types of circuit have numerous influential real-world applications, as students will discover through both simulation and hands-on work using NI ELVIS III.
