Question

Convert :- 1 Kwh Into Joules

Answer 1

Answer:

energy = power × time

so 1 KWh= 1000 × 3600 joules  ( because 1 KW= 1000 watt and 1 hour = 3600 seconds)

   1 KWh = 3600000 joules

               = 3.6 × 10⁶

Answer 2

Answer: 1 kWh = 3600000 Joules = 3.6 x 10^6 Joules = 3.6MJ.

Explanation:

As we know that,

Energy = Power × Time

So, 1 KWh= 1000 × 3600 Joules

(Since, 1 KW= 1000 Watts & 1 hour =

3600 seconds)

1 KWh = 3600000 joules.

= 3.6 × 10⁶ J = 3.6MJ.

(1MJ = 10^6Joules)
