 How much energy is stored in the capacitor?

Had the capacitor been connected to a 6.00-V battery, how much energy would have been stored?

### Capacitor Energy Storage

#### Problem Statement

(a) A 4.00-μF capacitor is connected to a 9.00-V battery. How much energy is stored in the capacitor?
- [Answer: _______ μJ]

(b) Had the capacitor been connected to a 6.00-V battery, how much energy would have been stored?
- [Answer: _______ μJ]

#### Explanation

**Capacitor and Battery Connection:**
- A **capacitor** is an electrical component that stores energy in an electric field. Its ability to store charge is measured in **farads (F)**.
- The energy (E) stored in a capacitor with a capacitance (C) and a voltage (V) applied is given by the formula:
  \[
  E = \frac{1}{2} C V^2
  \]
  Here, the energy is measured in joules (J), but often converted to microjoules (μJ) for convenience in small-scale circuits.

**Given Values:**
1. Capacitance, \( C = 4.00 \, \mu F \)
2. Voltage cases:
   - \( V_1 = 9.00 \, V \)
   - \( V_2 = 6.00 \, V \)

**Tasks:**
- Calculate the stored energy in microjoules (μJ) for each voltage case. 

Utilize the formula mentioned above for both scenarios to determine the energy stored in the capacitor.
