To determine the inductance of an unmarked inductor, you
Chapter 30, Problem 30.122(choose chapter or problem)
To determine the inductance of an unmarked inductor, you set up the circuit shown in FIGURE P30.78. After moving the switch from a to b at t = 0 s, you monitor the resistor voltage with an oscilloscope. Your data are shown in the table: Time (Ms) Voltage (V) 0 9.0 10 6.7 20 4.6 30 3.2 40 2.5 Use an appropriate graph of the data to determine the inductance
