3. A typical capacitor in an MP3 player has C = 9 F. If a charge 31 C is placed on the plates, what is the voltage across the capacitor?

4. Two capacitors with C₁ = 3.5 F and C₂ = 22.5 F are connected in parallel. If the combined charge on both capacitors is 23 C, what is the voltage across the capacitors?

5. Some charge is placed on a capacitor with C₁ = 32 F so that V = 19 V. The capacitor is then attached in parallel to a second capacitor with C₂ = 50 F. What is the voltage across the two capacitors?
