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, charge q, and potential difference V?
Options
A PEE = qV
B PEE = ½qV
Correct Answer
C PEE = CV²
D PEE = ½q²/V
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 15 lists the energy stored as 'PEE = ½qV = ½CV² = ½q²/C'. Option B, PEE = ½qV, is one of the correct forms.

Hint

Recall the factor of one-half that appears in the energy storage formulas for capacitors.
