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.
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.
