Show answer and explanation

Correct answer: 330 to 330

Explanation

KCL at the junction gives downward current10−8=2A. Use the long battery plates as positive terminals:the100Velement absorbs100×10=1000W, while the80Velement delivers80×8=640W and the15Velement delivers15×2=30W. Net absorbed power=1000−640−30=**330W**.
