- - - - It converts 50 J of electrical energy into light and heat per second
        
        Thus the 50W light bulb is brighter than the 10W light bulb
    - - It converts 10 J of electrical energy into light and heat per second
  - - - Time: 3 min = 180s
        Energy: 2700J
        Power: 2700J ÷ 180s = 15W
        
        Power (W) = Energy (J) ÷ Time (s)
    - - Time: 5s
        Power: 4 kW = 4000W
        Energy: 4000W x 5s = 20kJ
        
        Energy (J) = Power (W) x Time (s)
    - - Power: 0.5W
        Energy: 5000J
        Time: 5000J ÷ 0.5W = 10,000s
        
        Time (s) = Energy (J) ÷ Power (W)
- - - - The amount of electrical energy consumed by households and industries are very large.
  - - - Energy consumed (kWh) = Power (kW) x Time (h)
