SUMMARY

The discussion clarifies that two alternating currents with phases of 0.78 radians and 3.93 radians (0.78 + π) are indeed moving in the same direction over time. Although their instantaneous values may appear opposite due to their phase difference of π, the currents are effectively aligned when considering their directional flow from A to B and B to A. The graphical representation confirms this alignment, demonstrating that the currents will synchronize despite their phase difference.

PREREQUISITES
  • Understanding of phasors in AC circuit analysis
  • Knowledge of phase angles and their representation in radians

Hi all.

If I have a current going from A to B with a phase of 0.78 (radians) at time t, and a current going from B to A with a phase of 0.78+Pi = 3.93 at the same time t, does this mean that the currents are going the same way?

Thanks in advance.


Niles.

all that's really crucial is that their phase difference is pi, so their graphs over time will look like this:

(note, if you wanted it to perfectly match your situation, you could move the x-y axes over a pinch, but it would be the same result.)From the graphic it appears the two currents are always pointing opposite directions, however your problem states that one current is "from A to B" and the other is "from B to A" so one of them will be flipped and line up with the other one. So they do go the same direction over time.

Thanks for taking the time to plot the graphics and for answering.

Have a happy New Year.
