Description

Electric circuit analysis

GSB 3

Complex impedances for each loop are:
10+200i
-200i

-200i
(200-30)i

Voltages are:
5
0

Output values for current are:
0.0372 + 0.1311i
0.0437 + 0.1543i

Matrices [A], [B] and [C] can be read out by pressing A, B, or C

Note A has been transformed to a 4x4 matrix by the f MATRIX 2 operation.
