Re:

Kilowatt hour (kWh)

kWh

is the symbol or unit of energy stand for “kilowatt hour”. In the

billing of the energy meters, this unit is to be used and in joules it equals “3.6

MJ (Mega Joules)”. Basically, it is the watts consumed by users in kilo i.e.

kw and multiplied it to time in hours.

For example,

if we have a 1000W electric

appliance, and we operate it for 60 minutes, then after that time the energy

that utilized by apparatus will be 1KWh.

And similarly, for a 200-watt light

bulb, it takes 5 hours to mound on 1kWh of energy.

On the other hand, A 2000-watt electric

appliance will utilize the energy of 1kWh and remain “ON” for just 30 minutes. While

on the other hand, a 40-watt thing remains “ON” for 25 hours before it utilized

1kWh.

It is very hard to be conscious,

because there have been different wattages, on similar appliances, but here

some examples of 1kWh:

I.

Ironing the

clothes with a 1000-watts iron for 1 hour.

II.

An immersion

heater (2500 watts) “ON” for 25 minutes

III.

Watching TV for

three hours consumes (300-500 watts)

IV.

Using laptop

for whole day consumes (20-50 watts)

V.

Deep freezer

(300-600 watts) for three hours.

VI.

Broad band

router takes 7 to 15 watts for five days.

Besides

the rating and the consumption of the energy by the appliances, Kilowatt hour

be helpful to understand the following facts, like your bills are to be

calculated by the energy suppliers, how they can evaluate the billing of

numbers of users. Mostly appliances take more electricity than the others take

less, what is the reason behind it. Why the appliances are not to be kept on standby

mode after using them but be turned off.
