1. The problem statement, all variables and given/known data 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.
