Find Io in the network in Fig. P3.15 using nodal analysis. 1 k 1 k 2 k 4 mA 6 V 2 mA Io + Figure P3.15

4. Find the equivalent resistance R ab for these circuits: Solution: 5. Use the node voltage method to find the power developed in the 20V source. Is there a supernode in this circuit If so, identify it. There is a supernode and a quasi-supernode present in the circuit. The supernode is shown surrounded by a dotted line. As a result of these, There are only two independent nodes (in addition to the reference node) in the circuit….so there will be only two node equations:
