Two students use Kirchhoff's loop rule to write an equation for a single closed loop containing an ideal battery of emf \(\varepsilon\) and two resistors of resistance \(R_1\) and \(R_2\). Student 1 traverses the loop in the clockwise direction, which aligns with the direction of conventional current, and records the potential difference across each resistor as \(-IR\). Student 2 traverses the identical loop in the counterclockwise direction, opposite to the conventional current, and records the potential difference across each resistor as \(+IR\). Which of the following statements provides the correct physical justification for whether both students can obtain the correct current?
