kw and multiplied it to time in hours.For example, if we have a 1000W electricappliance, and we operate it for 60 minutes, then after that time the energythat utilized by apparatus will be 1KWh.And similarly, for a 200-watt lightbulb, it takes 5 hours to mound on 1kWh of energy.On the other hand, A 2000-watt electricappliance will utilize the energy of 1kWh and remain “ON” for just 30 minutes. Whileon the other hand, a 40-watt thing remains “ON” for 25 hours before it utilized1kWh.It is very hard to be conscious,because there have been different wattages, on similar appliances, but heresome examples of 1kWh: I. Ironing theclothes with a 1000-watts iron for 1 hour. II.

An immersionheater (2500 watts) “ON” for 25 minutes III. Watching TV forthree hours consumes (300-500 watts) IV. Using laptopfor whole day consumes (20-50 watts) V. Deep freezer(300-600 watts) for three hours. VI. Broad bandrouter takes 7 to 15 watts for five days.Besidesthe rating and the consumption of the energy by the appliances, Kilowatt hourbe helpful to understand the following facts, like your bills are to becalculated by the energy suppliers, how they can evaluate the billing ofnumbers of users.

Mostly appliances take more electricity than the others takeless, what is the reason behind it. Why the appliances are not to be kept on standbymode after using them but be turned off.
