## Electrical Energy
Electrical energy is power consumed over a period of time.
### Formula
**E = P * t**
In practical units: **kWh = W * hours / 1000**. In SI units: **Joules = Watts * seconds**.

Exemplo Resolvido
A 100 W light bulb running for 5 hours.
- E = P * t
- E = 100 * 5 = 500 Wh
- E = 0.5 kWh
- E = 100 * 5 * 3600 = 1,800,000 J
