Circuit behavior with internal resistance and switch Steps:

• Identify the circuit configuration from the diagram: cell with internal resistance r, external components with currents I1 and I2 labeled.
• With switch open, calculate initial currents using Ohm's law: total I = E / (r + R_eq_open).
• When switch closes, it alters the equivalent resistance, typically adding a parallel path.
• Re-calculate currents: change in R_eq affects I1 and I2 based on their positions.

Not enough information: The diagram is not provided, so the positions of I1, I2, and the switch cannot be analyzed to confirm effects.

Final answer: Not enough information.
