1) Three capacitors (4.0, 6.0, and 8.0 µF) are connected in series across a 50.0-V battery. Find the voltage across the 4.0-µF capacitor.
2) A 3.0 µF capacitor and a 4.0 µF capacitor are connected in series across a 46.0 V battery. A 15.0 µF capacitor is also connected directly across the battery terminals. Find the total charge that the battery delivers to the capacitors.
3) A 3.00-µF and a 5.00-µF capacitor are connected in series across a 30.0-V battery. A 10.00-µF capacitor is then connected in parallel across the 3.00-µF capacitor. Determine the voltage across the 10.00-µF capacitor.
