Kirchoff's Current Law

In this lab, students will learn about Kirchoff's Current Law (KCL). KCL states that the sum of the currents flowing into any junction in a circuit is equal to the sum of the currents flowing out of it. Kirchoff's Circuit Law is a fundamental law that allows us to analyze parallel circuits and is often combined with Ohm's law and Kirchoff's Voltage Law to solve for unknown values in a circuit. This lab gives students the opportunity to calculate unknown values using Kirchoff's Current Law and then confirm those values by building a real circuit using the NI ELVIS III.
