From the diagram above, calculate the energy stored in the capacitor

From the diagram above, calculate the energy stored in the capacitor
  • A.
    4.0 x 10(^{-2})J
  • B.
    4.0 x 10(^{-4})J
  • C.
    8.0 x 10(^{-4})J
  • D.
    8.0 x 10(^{-2})J
Correct Answer: Option B
Explanation

c = 8µF, v = 10v
Energy stored = (frac{1}{2}) cv2
= (frac{1}{2}) × (8 × 10− 6) × 102
= 4 × 10(^{-4})
