EMS - HOW YOU ARE BILLED CONT'D

Electricity Bills

 

For better understanding, let's break this down further. Let us say you are charged N20 Kw/Hr.

 

Here are approximate power ratings of some domestic appliances:

 

Energy Lamp: 20w

Flat screen TV: 200w

Ceiling Fan: 200w

Big Fridge: 400w

Iron: 1,000w

Big Freezer: 800w

A. C.: 1,200w

 

Now, let us say in a day, a family leaves 5 energy lamps on for 10 hours, Big freezer on for 10 hours, TV for 5 hours and you use your Iron for 2 hours; here is what you will pay for that day.

 

Energy consumed is calculated as follows:

Lamp is 5*20=100w or 0.1Kw Charge for 10 hours is 20*10*0.1=N20

 

Freezer is 800= 800/1,000= 0.8Kw so Charge for 10 hours is 0.8*20*10= N160

 

TV is 200=200/1,000=0.2Kw So charge for 5 hours is 0.2*5*20= N20

 

Iron is 1,000 = 1,000/1000=1Kw So the charge for 2 hours is 1*20*2= N40.

 

We then add together as 20+160+20+40 =N240 for that day.

 

Now you know the secret!

 

I hope the Maths is simple enough?

Questions please!
