Following points may be noted dependent sources are voltage or current sources whose output is function of another parameter in the circuit. There are certain network theorems, which when applied to the solutions of electric networks, either simplify the network itself or render their analytical solution very easy. Any twoterminal dc network can be replaced by an equivalent circuit. Dc networks theorems electrical network license scribd. Article pdf available october 2012 with 1,542 reads.
