Voltage Direction Versus Current Direction
Assuming the directions of current and the polarities of voltages shown in Figure 2.44 refer to the true (positive) values, do the following voltage/current labels conform to how passive elements should be referenced?

The blue check mark means that this solution has been answered and checked by an expert. This guarantees that the final answer is accurate.
