SUMMARY

The polarities of v3 and v2 in Figure 3.8 are determined by the directions of the currents I3 and I2. The discussion confirms that the polarities are influenced by the respective current directions, which also applies to I2 and I4. This relationship is crucial for understanding the circuit's behavior and functionality.

Please have a look on the Figure 3.8 in bottom right corner. What defines the polarities of v3 and v2? Is it the directions of I3 and I2? Please tell me. Thank you

Cheers

Yes, sure it is.
The same for i2, i4.
