Kilowatt-hour definition

Kilowatt-hour is an energy unit (symbol kWh or kW⋅h).

One kilowatt-hour is defined as the energy consumed by power consumption of 1kW during 1 hour:

1 kWh = 1kW ⋅ 1h

One kilowatt-hour is equal to 3.6⋅106 joules:

1 kWh = 3.6⋅106 J

The energy E in kilowatt-hour (kWh) is equal to the power P in kilowatts (kW), times the time t in hours (h).

Answer 2

Answer:

1 kilowatt hour = 3600000 joules

Explanation:

1 kW  =1000 sJ            

1 h =3600 s

∴  1 kWh =1000sJ×3600 s=36×10×10×10×1 0×10×10  J
