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 (μs) ........................Voltage (V)0.........................................9.010.......................................6.720.......................................4.630.......................................3.240.......................................2.5

Use an appropriate graph of the data to determine the inductance.
