Download LC Circuits and Resonance Experiment (ENGR 262L Lab #10) - Prof. Harold R. Underwood and more Lab Reports Electrical Circuit Analysis in PDF only on Docsity! Circuit Analysis Lab (ENGR 262L) Lab #10 (based on Exp #8 in Tsividis): LC Circuits and Resonance Preparation: Read section on Resonant Circuits in Tsividis (pp. 62-63) Lab Partners: You may work together with a partner at one lab station. Equipment & Components (each lab station): Digital Multimeter (DMM) [Extech model 430] Function Generator (FG) [BK Precision type] Oscilloscope (scope) [BK Precision model 2522 or 2522B] with scope probes Inductor [470 H 10% Vishay/Dale Molded], Resistor [10 K] Variable Capacitor [10-150 pF Sprague/Goodman FILMTRIM Trimmer] Jumper Wires, Connecting Wires and Cables, etc. Procedure: Read procedure in Tsividis, pp. 62-66, but skip steps 2, 8 &10. See below. Lab Reports: One report per group due by the end of the lab period. Include all parts of your report as indicated below, in Lab Report Format. Lab Report Format (for Experiment #7): 2 pts Heading: Lab #, Title, Date Author’s Full Name (printed), roles Partner’s Full Name (printed), roles 2 pts Objectives: Experiment with circuits containing capacitors and inductors. Observe resonance, and the related fact that such circuits respond better to certain frequencies (a property called selectivity). 1 pt Diagrams: see Tsividis, pp. 62-64, Figures 1-3, see also modified version of circuit (Fig. 3*) on board, without transformer 1 pt Equipment: state from list above; indicate model # and unit # used 10 pts Results: record any observations, tables, plots, answers to questions or other results (such as measurements and/or calculations) as indicated in each step of the procedure 4 pts Summary & Conclusions: Summarize what you learned in one paragraph, highlighting anything especially new to you and any specific conclusions you arrived at as a result of this work. Include any ideas for creative extensions you may have. Put Signatures of Author & Partner at end of report Additional notes on procedure steps: 1. Ignore “The inductor in this experiment uses a ferrite material…” 2. Skip this step. You will not use transformers, rather a molded coil inductor. 3. See board for modified Figure 3*. Vary signal frequency from 0.2 to 2.0 MHz. 4. A linear plot is OK. 8. Skip this step. 9. Disconnect FG from circuit, and replace connection with a long black jumper wire at the free end of the 10 K resistor. 10. Skip this step. 11. Connect a long black jumper wire to the FG.
