Material for this Lab Experiment 6 Manual General Lab Documents TOC and Introduction Appendix A: Error Analysis for the Physics Labs Appendix B: Introduction to Spreadsheets and EXCEL 2010 Problem Statement: Consider the following: Part (a) What is the magnitude of the impedance in k Ohm of a 30.0 mH inductor at a frequency of 25 kHz? Numeric : A numeric value is expected and not an expression. Material for this Lab Experiment 6 Manual General Lab Documents TOC and Introduction Appendix A: Error Analysis for the Physics Labs Appendix B: Introduction to Spreadsheets and EXCEL 2010 Problem Statement: A series LRC circuit is driven at a frequency which is much greater than the resonant frequency with a sine wave voltage source with an amplitude of 1.0 V. Part (a) What is the approximate voltage amplitude across the inductor? Numeric : A numeric value is expected and not an expression.

Solution

Problem 8: The impedence of an inductor L, with frequency is given as  L

Hence, for the given inductor, Impedence = 30 x 10^-3 x 15 x 10^3 = 450 Ohms = 0.45 K

Problem 9: For an LRC circuit driven at frequency much greater than that of the resonant frequency. The net voltage amplitude for each of the components is same as the source amplitude.

Hence ther required value is 1 volt
