Problem: Suppose you have a 9.00-V battery, a 2.00-μF capacitor, and a 7.40-μF capacitor Find the charge and energy stored if the capacitors are connected to the battery in series. .

FREE Expert Solution

Equivalent capacitance for series capacitors:

1Ceq=1C1+1C2

The charge stored in a capacitor:

Q=CV

Energy stored in a capacitor:

U= 12CV2

Ceq = (1/C1 + 1/C2)-1 = (1/2.00 + 1/7.40)-1 = 1.57 μF(10-6F/μF) = 1.574 × 10-6 F
