Make sure you are on the Natural Response side. 2. Find the parallel RLC column. 3. Use the equations in Row 4 to calculate and 0. 4.

Applying KVL, we can write: Substituting the i-v relation for a capacitor, we obtain: We can clean this up a bit by dividing by RC: Where: Nature response of an RC circuit (3) To directly solve v(t), replacing the charged capacitor by a Norton equivalent in the s-domain..

When an RC or RL circuit has reached a constant voltage and current and is disconnected from a power source it reaches a state called zero input response or natural response. The resulting reaction of the system for an RC circuit is the function: Engineering Circuits - Vol 5 - RC & RL Circuits Lesson 8 - RC Natural Response Circuit Problems, Part 1 (Engineering Circuits) This is just a few minutes of a complete course. The homogeneous solution is also called natural response (depends only on the internal inputs of the system).

Overview This gives us the general form of the natural response, $v_n = K_n\,e^{-t/\text{RC}}$ The natural response is an exponential curve whose speed of descent is determined by the product $\text{RC}$. We still have to figure out the specific value of $K_n$.

but i'm the slow learner. so to fellow mentors, pls verify my method the objective is to measure the value of C from the decaying graph (picture) using the basic rc natural response formula thats on the page i'm opening infront of me right now (red text below). • A natural response. • A transient response. • A forced response. The other solution of the ODE is the particular solution or forced response xp(t), due to the forcing function. 7.1 The Natural Response of an RC Circuit nThe natural response is due to the initial condition of the storage component ( C or L). nThe forced response is resulted from external input ( or force). nIn this chapter, a constant input (DC input) will be considered and the forced response is called step response.

2.4.2: RC Circuit Natural Response Revision: June 12, 2010 215 E Main Suite D | Pullman, WA 99163 (509) 334 6306 Voice and Fax Doc: XXX-YYY page 1 of 9 Copyright Digilent, Inc. All rights reserved. Other product and company names mentioned may be trademarks of their respective owners. Overview We put some charge on a capacitor in an RC circuit and observe what happens to it. The behavior of the current and voltage is called the natural response. This gives us the general form of the natural response, $v_n = K_n\,e^{-t/\text{RC}}$ The natural response is an exponential curve whose speed of descent is determined by the product $\text{RC}$. We still have to figure out the specific value of $K_n$.
