Question

Chapter 20 Laboratory Application Assignment 6 Figure 20-17 In this lab application assignment you will examine how the inductive reactance, X, of an inductor increases when the frequency, f, increases. You will also see that more inductance, Lat a given frequency results in more inductive reactance, X. Finally, you will observe how X values combine in series and in parallel L=100 MH V-5 Vrms Equipment: Obtain the following items from your instructor • Function generator • 33-mH and 100-mH inductors • DMM DC Resistance, r. of a Coil With a DMM, measure and record the de resistance of each inductor. Set the DMM to the lowest resistance range when measuring (33 mH) - (100 ml) - Vrms 1-5 kHz Inductive Reactance, X Refer to Fig. 20-17 a. Calculate and record the value of x for each of the following frequencies listed below. Calculate X as 2TL x = 0,314 @f=500 Hz X = 0.63 @f= 1 kHz x 1. 2 k @f=2 kHz Connect the circuit in Fig. 20-170 Set the voltage source to exactly 5 Vrms. For each of the following frequencies listed below, measure and record the current, 1 (Use a DMM to measure 1) Next, calculate X as V/L. 1 - 15.9mA@f=500 Hz: X-0.314 1- 7.M @f=1 kHz; x = 0.33 3.9 @f-2 kHz; X 128 Refer to Fig. 20-17b. With the frequency. f, set to 5 kHz, calculate and record the value of X for each of the following inductance values listed below. Calculate X as 2 L x 056 when L= 33 mH X = 3.11 when L-100 mH Connect the circuit in Fig. 20-175 Adjust the frequency, f, of the function generator to exactly 5 kHz. For each inductance value listed below, measure and record the current, L (Use a DMM to measure 1.) Next, calculate X as V/I. 1 = 9.81m4 when L=33 mH: X - 103 1. Sam4 when L= 100 mH; X = 3.112 Is X proportional or inversely proportional to the value of inductance? 1 How do the experimental values of X compare to the calculated values? They are commorable Dased on your experimental values, what happens to the value of X every time the frequency. (.doubles? Goes De ortional or inversely proportional to the frequency? Did the de resistance, r, of the inductors affect any of your Is X proportional or inversely proportiona measurements? If so, explain.

just need a check of the answers and if wrong can you show me the math to correct it. thanks
