PHY 102 Coulomb's law and Electric Fields Objective Question
Take CBT

Question

Which of the following expressions correctly represents the energy (PEE) stored in a capacitor of capacitance C with charge q and potential difference V?
Options
A PE<sub>E</sub> = qV
B PE<sub>E</sub> = ½qV²
C PE<sub>E</sub> = ½CV²
Correct Answer
D PE<sub>E</sub> = qV/C
Correct Answer

Option C is the correct answer.

Detailed Explanation

The text states: 'The energy (PEE) stored in a capacitor of capacitance C that has a charge q and a potential difference V is PEE=½qV=½CV²=½q²/C' (Page 15, Equation 25.12). Option C is one of the correct forms.

Hint

Look at the 'Energy Stored in a Capacitor' section and the corresponding equation.
