I Review To determine the inductance of an unmarked inductor, you set up the circuit shown in the following figure. After moving the switch from a to b at t = 0s, you monitor the resistor voltage, VR. with an oscilloscope. Your data are as follows: Part B Time, t (us) Voltage, VR (V) In (V) 9.0 10 6.7 20 4.6 2.0 30 3.2 40 2.5 1.6- (Figure 1) In (V)=(-33000 s")+ 2.20 1.2- 0.8 0.00000 (s) 0.00001 0.00002 0.00003 0.00004 Graphing either In (VR) versus t or t versus In (VR) gives a straight line. In the graph shown above, we chose to plot In (VR) on the vertical axis and t on the horizontal axis. From the equation for the line of best fit given, determine the inductance L. Express your answer to two significant figures and include the appropriate units. Figure 1 of 1> > View Available Hint(s) HẢ 6 ở O B ?
