In this problem you will calculate the inductance of an inductor from a current measurement taken at a particular time. Consider the L-R circuit shown in (Figure 1). Initially, the switch connects a resistor of resistance R and an inductor to a battery, and a current Io flows through the circuit. At time t = 0, the switch is thrown open with the motion indicated by the arrow, removing the battery from the circuit. Suppose you measure that the current decays to I1 at time tį.
