(2). Consider the 4 bus network with the given impedances below. Find the bus admittance matrix. The lines 1-4 and 1-3 have half line charging admittances of j0.01 p.u. and j 0.003 p.u. respectively. The shunt capacitor at bus (4) has an admittance of j 0.03 p.u. The line data is given below. The left bus is taken as the tap side of the transformers.
