Question

15. How many joules of energy is consumed if the electrical meter shows 200 units of energy?
(1 Point)
O A) 36 x 100 joules
(B) 720 x 100 joules
O (C) 46 x 100 joules
O (D) 540 x 100 joules​

Answer 1

Explanation:

The unit of electrical energy is kWh. 1 kWh is the energy used in one hour at a rate of 1000J/s. 400 units= 144× 10^7

Answer 2

Explanation:

1 unit = 1kwH

= 1000w ×3600s

= 3.6 × 10 ^6 joules

so in 200 units = 200 ×3.6× 10^6

= 720 x 10^6 joules
