Question

convert 1 kwh into joules

Answer 1

1kwh=1kw×1h
=1000w×3600s
=3600000w sec
=3.6×10^6 joule

Answer 2

Answer: 1 kWh, or the amount of energy transferred over the course of an hour from a power output of 1000 watts, is equivalent to one kilowatt (1 kWh) (i.e., joules per second). So, 3,600,000 joules of energy are transferred for each kWh (work).

Explanation:

∵1kWh = 1kw× 1h
Since there is 1000W in 1kW so we can write 1kW as 1000W
1hr = 60min  1min= 60 seconds thus 1hr = 60×60= 3600s

1kWh = 1000W×3600s

1kWh = 3600000 W sec

1kWh = 3.6×10⁶joule

• A kilowatt hour (kWh) is said to be a unit of measurement for your hourly energy use, whereas a kW is a unit of power.
• Kilowatt that is sometimes known as kW, is a unit of measurement for electricity. Therefore, 1,000 watts make up one kilowatt.
• Our electricity company bills us according to the number of kilowatt hours we use (kWh).
