Potential divider voltage division

Steps:

• The circuit has three resistors in series across 6.0 V: variable R and two fixed resistors (values not specified).
• Voltmeter reads 2.0 V across an unspecified part of the divider.
• Without the diagram showing fixed resistor values or voltmeter position, calculate potential drop ratios using V = IR.
• Total resistance and current cannot be determined numerically.

Not enough information.

Why A is correct:

• Cannot verify; lacks fixed resistor values or voltmeter placement per potential divider formula V_out = V_in × (R_section / R_total).

Why the others are wrong:

• B: Same issue; insufficient data to compute.
• C: Same issue; insufficient data to compute.
• D: Same issue; insufficient data to compute.

Final answer: Not enough information.
