Concept

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 parallel

FREE Expert Solution

Equivalent capacitance for parallel capacitors:

Ceq=C1+C2

The charge stored in a capacitor:

Q=CV

Energy stored in a capacitor:

U= 12CV2

Ceq = C1 + C2 = 2.00 + 7.40 = 9.40 μF(10-6F/μF) = 9.40 × 10-6 F
