A) Charge a 3 microfarad capacitor by hooking it to a battery (a voltage difference supplier) that has a potential difference of 15 volts. a) What is the charge on one the capacitor plates? b) If the plate separation is 2 x 10-6 meters, what is the electric field between the plates? c) How much energy is stored?

B) Leaving the battery connected, you insert a dielectric with a constant of 3.7 between the plate of the capacitor. a) What is the charge on one of the plates now? b) What is the voltage difference between the plates? c) How much energy is stored?

C) Starting with the situation in A), don’t insert a dielectric. Rather, disconnect the capacitor from the battery and connect the (still charged) capacitor to another uncharged capacitor with a value of 7.0 microfarads. a) What is the charge on each capacitor? b) What is the voltage across the 7.0 microfarad capacitor?
