Question

1 kwh is equal please solve question​

Answer 1

Answer:

1 kilowatt hour is the energy produced by 1 kilowatt  power source in 1 hour.

1kWh=1kW×1hour=1000×3600W.s

⟹1kWh=3.6×10  

6 J

⟹1kWh=3.6MJ

Answer 2

Explanation:

taking, power = 1 KW

time = 1 h

now,

energy = power × time ( energy = E)

=> E = 1 KW × 1 h ———— eq 1

=> E = 1000 W × 3600 s ( seconds = s)

=> E = 3600000 J (Jules = J)

=> E = 3.6 × 10⁶ J ———— eq 2

from eq 1 and eq 2

we get

1 KWh = 3.6 × 10⁶ J
