Describe the experimental setup and how the decay constant was measured. From the decay curve, measure the time constant 1:; where ris time need for the signal to decrease e=2.718 times. To do this, first estimate the maximum voltage across the capacitor VG max. Then calculate VG max/e, and find from the graph how much time is needed for the signal to change from Vc max to Vc m/e. Compare the measured rwith the theoretical value r=RC. Measure the half-time, I'M, necessary for the voltage across the capacitor to fall from its maximum value Vc max to one half of that value, Vc max/2. Calculate r from rm: 1' = t1;2/l(2), and compare it with the previously found value. Referring to the minimum voltage of the trace as 0 V, measure VC(t) from the graph for t=0.0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, and 4 ms. Calculate Vc(t)/ Vc max and lanc(t)/ Vc max) for each of the measured values. Plot ln(Vc(t)/ Vc max) vs t, with t on the horizontal axis. Calculate the slope of this graph, and calculate 1-: 1[slope), and compare it to the previously obtained value. Conclusions In a short paragraph, describe the essence of the physical phenomena studied in this lab and the results of those studies
