Description : How do you solve -12 z and divide 3 for z.?
Last Answer : Without an equality sign the given expression is not an equationand so therefore a solution is not possible.
Description : What technique is used to solve load flow problems using Z-bus (Bus impedance matrix)?
Last Answer : The formulation of load flow problem using Zbus employs Diakoptics techniques which is actually the piecewise solution of the power system problem by using tearing off technique.
