A Capacitor Is Attached Across a Battery and Charged

question 55

Multiple Choice

A capacitor is attached across a battery and charged. Then the battery is removed leaving the capacitor charged. The positive lead of the capacitor is then connected to one lead of a previously uncharged identical capacitor, and then the other lead of the charged capacitor is connected to the other lead of the second capacitor. How does the energy E₀ stored in the originally charged capacitor compare to the energy E_f stored in the connected capacitors?

• A) E₀ = 2E_f
• B) E₀ < E_f
• C) E₀ = 4E_f
• D) E₀ = E_f
