question 117

Multiple Choice

A 6.0-μF air-filled capacitor is connected across a 100-V potential source (a battery) .After the battery fully charges the capacitor,it is left connected and the capacitor is immersed in transformer oil,which has a dielectric constant of 4.5.How much additional charge flows from the battery onto the capacitor during this process?

• A)1.2 mC
• B)1.7 mC
• C)2.1 mC
• D)2.5 mC
