# A 80-pF capacitor is immersed in silicone oil...?

When the capacitor is connected to a 24-V battery, what will be the charge on the capacitor?

How much energy is stored in the capacitor?

ANY HELP PLEASE! I was absent for this lecture and am having a difficult time figuring this out.

Update:

A 80-pF capacitor is immersed in silicone oil, which has a dielectric constant of 2.6.

sorry forgot to put the full question in.

assuming it was an air dielectric and its capacitance went up by 2.6 times

Q=CV = 80e-12*2.6*24 = 5e--9 coulombs

energy storage = 1/2 C*V^2 = 1/2*5e-9*24 = 60e-9 Joules
