1. This small group activity is designed to help upper-division undergraduate students understand the response of an LRC circuit to a superposition of sinusoidal voltages.
  2. Students predict the response of a series LRC circuit to a single harmonic voltage and calculate the response of the circuit given a graph of admittance amplitude and phase.
  3. The whole class discussion focuses on the interpretation of the graphical representation of admittance (amplitude/phase) and how to build the response of a multiple-frequency driver from the individual responses.
