RC Circuits

In this lab, students will learn about resistor-capacitor (RC) circuits. These are circuits in which a resistor is placed in series with a capacitor and used to control the rate at which the capacitor charges or discharges. Like capacitors themselves, RC circuits have many applications in real-world circuitry. Students will make calculations for a given RC circuit and then build, modify, and measure that circuit with the NI ELVIS III. Students will also gain experience with two instruments: the function generator and the oscilloscope.

This is lab 7 of 10 in the course, Introduction to Circuits.


After completing this lab, students will be able to:
  1. Discuss the purpose and behavior of RC circuits.
  2. Calculate the time constant of an RC circuit, measure the charging of an RC circuit, and confirm the time constant for that circuit.
