Document Summary
Use nodal analysis on the circuit in fig. 3. 1 to determine: the current ix, the power supplied by the voltage source. Note that the tops of both the 2 and 4 resistors are at node v. at this node, kcl gives. The power supplied by the 24 v source is p=iv, where i is the current flowing into its positive terminal, = = 2 24 = 48 (the minus sign confirms that the voltage source is a supplier of power. ) Use the nodal-analysis method to find v1 and v2 in the circuit of fig. 3. and then apply that to determine ix. Use cramer"s rule to find the voltage solutions. Using current in = current out, i7 + 3 = ix. Combining these 2 equations yields i7 = (v2 v1)/12 3. 3. 4 apply the supernode technique to determine vx in the circuit of fig. The combination of nodes v1 and v2 constitutes a supernode.
