#quExample  Electronics application of 3×3 System of Equations
Find the electric currents shown by solving the matrix equation (obtained using Kirchhoff''s Law) arising from this circuit:
math expression
??I1+I2+I32I1+3I23I2+6I3??=??0240??
Answer
We can write this as:
??120133106????I1I2I3??=??0240??
So we have:
??I1I2I3??=??120133106??1??0240??
Using a computer algebra system to perform the inverse and multiply by the constant matrix, we get:
I1=6 A
I2=4 A
I3=2 A
We observe that I1 is negative, as expected from the circuit diagram.
