@ahmed nasser

Looks like the Kirchhoff's voltage law.

https://en.wikipedia.org/wiki/Kirchhoff%27s_circuit_laws

Are you looking for something like this?

syms Vab Vbc Vca
eqn = Vab + Vbc + Vca == 0
S = solve(eqn, Vca)

[ahmed nasser]

@Sam Chak yes.this what i'm looking for

[ahmed nasser]

@Sam Chak I want an initial code that deduces the third voltage after reading from the sensors

[Sam Chak]

@ahmed nasser

Are you looking for something like the user input?

prompt1 = input('What is the value of Vab? ');
Vab = prompt1;

prompt2 = input('What is the value of Vbc? ');
Vbc = prompt2;

Vca = - (Vab + Vbc)

@Sam Chak Thank you very much ..Mr. Sam

[Sam Chak]

You are welcome. Take your time to explore MATLAB.

Answer 2

What is the code supposed to do with the three V-values ?

You can write

syms V_ab V_bc V_ca
eqn = V_ab + V_bc + V_ca == 0
result = solve(eqn,V_ca)

And now ?
