Verify Superposition Principle using Matlab, given a DC source of 100V, an AC source of 50V, 60Hz and three resistances, R1=10 ohms, R2=20 ohms and R3=15 ohms.

I created the circuit below and ran the program. Result:

2. Relevant equations

None, just running the program.

3. The attempt at a solution

Now, the Principle of Superposition states the total current in any part of a linear circuit equals the algebraic sum of the currents produced by each source separately. I am trying to verify the current flowing through R3 = 15 ohms resistance.

- I short circuit the DC voltage source and run the program. Result:

- I then short circuit the AC voltage source and run the program. Result:

As clearly can be seen, the Superposition Principle is not verified. I am unable to reason where the discrepancy is.
