Faraday's law characterizes the voltage drop across an inductor as di VL = L- dt where VL 1 H = 1 V s/A), i = current (A), and t = time (s). Deter- mine the voltage drop as a function of time from the follow- ing data for an inductance of 4 H. voltage drop (V), L = inductance (in henrys; t 0.1 0.2 0.3 0.5 0.7 i 0.16 0.32 0.56 0.84 2.0 solve it in matlab di Hint: Use the built-in function diff to approximate dx
