What is a Dual Network?Two electrical networks are said to bedual networksif themesh equationsof one network is equal to thenode equationof the other.The dual network is based on Kirchhoff Current Law and Kirchhoff Voltage Law. Applying Kirchhoff Voltage Law in the network A, above we get, Applying Kirchhoff Current Law in the network B, above we get, Here we have found that equations (i) and (ii) are similar in their mathematical form. Equation (i) is in mesh form and equation (ii) is in nodal
