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.

Exemple Résolu

A 100 W light bulb running for 5 hours.

  1. E = P * t
  2. E = 100 * 5 = 500 Wh
  3. E = 0.5 kWh
  4. E = 100 * 5 * 3600 = 1,800,000 J
