In this experiment we analyzed the transient response of RC and RL circuit. And compared the time in theory, simulation and experiment and find large errors in results. Major reason for these errors was the unavailability of desired equipment such as we need 3k ohm resistor but we find 3.3k ohm, we needed 47mH inductor but we got 60mH inductor, which was closest to the theory value. The tolerance of the components also contributed to the errors. We were measuring the results from oscilloscope that has maximum voltage resolution of 20mV hence error expected. Due to these factors the deviation between Lab 2:Study of the Transient Response of RC and RL Circuits With R=5K: Date/Time run: Measurement Value | 08/24/21 05:47:20 ~ [Xatthy ((L11),1.68m,1) Figure 2. 14: Time (t) at Current (I L1) 84.55149u 1.66mA Temperature: 27.0 1.2ma 0.2mA (A) trans.dat (active) a I4LL) 0.5ms § 1.5m 2.0ms Al: pou, 0. 9990m) Bas 0.000, 0.000) DIFF (A): o.800u, 0 3g Figure 2. 15: Current through inductor L1 with R = 5K Measurement Value MatNthY (KL1-1),0.99m,1) 2.
