1. This integrated laboratory activity is designed to help upper-division undergraduate students to investigate the single frequency response to the simplest driving force, to have hands-on experience with real electronic components and measuring devices, and to have a chance to synthesize in a write up.
2. Students were to measure the current response of the series LRC circuit to a sinusoidal voltage input at a series of frequencies about resonance frequency, To determine the complex admittance of the LRC circuit as a function of frequency, in amplitude/phase form, To estimate the quality factor $Q$ and the resonance frequency $\omega_1$ from admittance data, and to compare the experimental result to the model discussed in class.
3. The whole class discussion focus around issues of measurement and how to write a good lab report.
