Model the equation of a RLC circuit and solve it by Euler Method

Hi I need to develop a RLC model by Euler method and develop a grahp of current and voltage, something like shown in the image

I neet to use the values of

R=5

C=0.01e-6

L=0.5

h=0.00001

and it must start in zero

I have been trying but I can´t get the result shown in the picture, please, help me

Hello,

I understand that you are trying to simulate a RLC circuit and obtain the results as shown in the attached images.

The natural frequency of oscillation for series RLC circuit can be found from formula:

The values of R, L, and C provided by you, yields natural frequency () ≈2252 Hz.

From the waveforms of voltages and currents attached by you, the frequency of oscillation comes out to be approximately 150 Hz.

As a conclusion, with the above provided values of R, L and C, it is not possible to get the results as attached in the images.

Kindly try to readjust the value of R, L and C to get the desired results.

I have attached the MATLAB code file “RLC_Series_Ckt”, which solves the RLC circuit using Backward Euler method. I passed the values of R, L, C and h as provided by you. The results obtained by running the code are shown below.

You can readjust the values of R, L, and C in the code to get the solution you desire.

Hope this solves the issue.
