3. 500 W television used for 5 hours
4. 800 W electric cooker used for 1 hour. ​

Answer 1

Answer:

Television consumes more energy.

Explanation:

60W bulb used for 8 hours.

E = 60 x 8 = 480W

1000W speaker used for 2 hours

E = 1000 x 2 = 2000W

500W television used for 5hours

E = 500 x 5 = 2500W

800W electric cooker used for 1 hour

E = 800 x 1 = 800W

So 500W television used for 5 hours consumed more electric energy.
