Does Polarity and Current Direction Affect Energy Flow in AC Circuits?

[charminglystrange]

Homework Statement

How do the electrical currents in the arms of a network, containing resistors and batteries, alter if the connections to all the batteries are reversed?

Relevant Equations

n/a

I assume that because there is a resistance, the polarity of the voltage must be the same as the charge flow, and thus the current, in order for energy to flow in the same direction.
For instance, could I use the example of a light bulb (the resistor) plugged into AC lines; we know that if the current alternates, the voltage must also alternate to ensure energy does not vibrate back and forth, and flows into the light bulbs, so into the resistor.

However, am I oversimplifying the question here, and can I not apply this example?

Many thanks, and I welcome any feedback on asking questions; this is my first one :)

Hello cs, !

Charge symmetry makes all the currents change sign, and that is all. As long as the resistors are ideal...
And I take it we are talking stay state here (no huge sizes and high frequencies).

Many thanks, and yes, I think we can take the resistors to be ideal.
