    2. To calculate the power of the lamp, we can use the formula for power:

      P = Energy/Time

      Given:
      – Electrical energy consumed by the lamp = 1000 joules (J)
      – Time taken = 10 seconds (s)

      We’ll use these values in the formula to find the power (P) of the lamp:

      P = 1000J/10 s
      P = 100 W

      Therefore, the power of the lamp is 100 watts (W).
