The circuit simplification presented appears correct, but there is confusion regarding the use of ohms for all components, which complicates understanding impedance. The discussion highlights the importance of recognizing that the book is currently simplifying concepts for easier comprehension. A question arises about calculating Vb using the Voltage Divider Rule, with confirmation that the approach is correct but requires careful attention to parentheses in the formula. However, it is noted that merely rearranging components does not fulfill the requirement to combine impedances and currents as specified in the assignment. Overall, the focus remains on ensuring proper calculations and understanding of circuit simplification.
