Use a 5 V ideal source with 2 kΩ and 3 kΩ in series. The 3 kΩ resistor connects the middle node to ground. Assume no extra load and nominal resistances. Predict both voltage and power before selecting an answer. A correct voltage with an inconsistent current or power is not a complete solution.
Which pair gives middle-node voltage and total resistor power?
The series current is 5 V / 5 kΩ = 1 mA. The lower resistor drops 3 V. Total power is 5 V × 1 mA = 5 mW. The 2 V answer confuses upper drop with the middle-node voltage.
