EXAMPLE 8.5 Determine current I, for the network in Fig. 8.9. Solution: Although it may appear that the network cannot be solved us- ing methods introduced thus far, one source conversion, as shown in Fig. 8.10, resuls in a simple series circuit, It does not make sense to convert the voltage source to a current source because you would lose the current I in the redrawn network. Note the polarity for the equivalent voltage source as determined by the current source. ‘For the source conversion:
