Question

define 1 killo watt hour​

Answer 1

Answer:

1 Kwh can be defined as the amount of electrical energy consumed when a 1000 watt electrical appliance is used for an hour. The unit of energy is watt. 1 Watt = 1 Joule /second. One kilowatt hour is 3.6 megajoules. It is the amount of energy converted if work is done at the rate of 1000 watts per hour.

Answer 2

Answer:

1 kilo watt hour is the energy consumed by an appliance in one hour.  in one kilo watt hour(1kWH), 1000 watts(1kW) is consumed in one hour(3600seconds).  It used to measure electrical energy.

Explanation:

Numerically it can be defined as :

1kwh

= 1 kW * 1hr

= 1000w*3600s  

= 1000 J/s * 3600s                  -     ( 1 watt = 1 joule/ 1 sec)

= 3.6* 10^6 J

therefore , 1kwh= 3.6*10^6 J
