question 69

Multiple Choice

A 10-μF capacitor in an LC circuit made entirely of superconducting materials (R = 0 Ω) is charged to 100 μC. Then a superconducting switch is closed. At t = 0 s, plate 1 is positively charged and plate 2 is negatively charged. At a later time, Vab = +10 V. At that time, Vdc is

• A)0 V.
• B)3.54 V.
• C)5.0 V.
• D)7.07 V.
• E)10 V.
