4.2 – Impedance and Admittance Matrices
www.ittc.ku.eduThe admittance matrix is a N by N matrix that completely characterizes a linear, N -port device. Effectively, the admittance matrix describes a multi-port device the way that Y L describes a single-port device (e.g., a load)! But beware! The values of the admittance matrix for a

1.0 The Admittance Matrix C - Iowa State University
www.engineering.iastate.eduWe make several observations about the admittance matrix given in eqs. (6) and (7). These observations hold true for any linear network of any size. 1. The matrix is symmetric, i.e., Y ij =Y ji. 2. A diagonal element Y ii is obtained as the sum of admittances for all branches connected to bus i, including the shunt branch, i.e., ¦ z N k k i Y ...
