Hi! This is my first post in eda.

I am revising my electrical principles for circuits so I am studying Principles of Electric circuits Electron Flow by Floyd. In pg. 358 an example is given of a bridged-T circuit and Loop current method is applied to find the currents of the loops.

It finds in pg. 358 that I2 has a negative value so I2 is in the opposite direction of IA; the positive side of the resistor is the right side. Why is that? Shouldn't be the positive side the left side of the resistor?

Look at attachments.
