Asked in NUMS 2019 (cancelled sitting) 2019Moderate

The energy stored in the capacitor is written as:

Correct answer: A. ½ CV2

  • A. ½ CV2
  • B. ⅓ CV2
  • C. CV2
  • D. None of these

Explanation

The energy stored in a capacitor is given by the formula:U = 1/2 CV2where U is the energy stored in the capacitor, C is the capacitance of the capacitor, and V is the potential difference across the capacitor.

About Capacitors

Capacitors store electric charge and energy in an electric field between conductors. Work includes capacitance, the relation Q = CV, dielectric materials, charging and discharging, energy formulas, and combinations of capacitors in series and parallel. Electric potential difference is needed to understand why charge and stored energy change.
