In the circuit shown above, the switch S is open, the capacitor is uncharged, and the current through the battery is 0.5â€‰A.

In which switch position, open or closed, can the current be the same in the left and right branches, and why?

Neither position, because the resistors in these branches have different resistances.
Only immediately after the switch is closed, because then the equivalent resistance of the middle and right branches equals that of the left branch.
Both positions, because the current in the middle branch will be zero at some time for both positions.
Only when the switch is open, because then the resistors are in series.
