As the dielectric, he used strontium titanate (k = 310). Dr. Doom plans on using his battery with an EMF = 20kV connected to a set of 20 parallel 100 Mohm resistors in series to charge the capacitor.
1) How long will it take to "fully" charge the capacitor?
2) How much charge will the capacitor hold when it reaches maximum voltage?
3) How much energy is stored in the charged capacitor? How much energy is lost during the process of charging the capacitor?

Is this correct?

Actually, I think it was exactly right

So do we just both answers and specify?

Yes, I would assume...

Let's continue with the next question.

### Re: Circuit Lab B/C

When connected to a 9.0 volt battery and a copper wire (resistivity 1.68e-8 ohm-meters, diameter 2.0 mm), a capacitor charges to a potential drop of 6.0 volts in 81.89 ps. The capacitor's plates are square, 5.0 meters to a side, and are separated by 1.0 millimeter of air (k=1.0). How long is the wire?

### Re: Circuit Lab B/C

Resistors R1, R2, and R3, voltage source V1, and current source I1 are arranged as in the diagram. These circuit elements have the following values:

R1: 5Ω
R2: 3Ω
R3: 10Ω
V1: 8V
I1: 6A

What is the voltage across and current through each of the three resistors?

That looks right! (Although, if this were a test, you might want to evaluate those fractions and truncate them to 1 sig fig.) Your turn!
