The formula to convert capacitance and voltage into energy in watt-hours (Wh) is:
\[ \text{E (Wh)} = \frac{C \cdot V^2}{2 \cdot 3600} \]
Where:
The energy stored in a capacitor is the electrical potential energy held within the electric field between the two plates of the capacitor. This energy can be released to power circuits and is especially useful in applications requiring quick bursts of energy. The unit of energy for capacitors is typically joules, but it can be converted to watt-hours for comparison with other energy storage devices like batteries.
Let's assume the following values:
Using the formula:
\[ \text{E (Wh)} = \frac{10 \times 12^2}{2 \times 3600} \approx 0.0200 \]
The Energy (E) is approximately 0.0200 Wh.
