SOLVED: Using Mathematica, overlay on the same plot graphs of current rise and decay versus time (i(t)) in an RL circuit in which V = 100 V, R = 75.0 Ω, L = 60.0 mH and 0 < t < tL. (You will measure these quantities in the lab exercise.) On each graph, mark by hand the position of one time constant on the time (horizontal) axis and the corresponding current on the vertical axis. In your Lab Notebook, describe the behavior of current in an RL circuit.
