This video shows how to solve for the Natural response of a first order RC circuit. It has the following chapters: (00:00) [1] Introduction (01:40) [2] Identify natural response (03:26) [3] Solve for natural response parameters (09:04) [4] Mathematica (10:01) [5] PSPICE (10:59) [6] Solve for other voltages/currents It discusses: (a) In Section 2: How to distinguish between natural and step response. (b) In Section 3: How to solve for the parameters that make up the natural response. (c) In Section 4: How to use Mathematica to plot the natural response. (d) In Section 5: How to use use PSPICE to verify the solution to the natural response. (e) In Section 6: How to solve for other voltages/currents in the circuit using the natural response.
