Electrical Knowledge: Did You Know ??

Hi everyone!

Do you know what contributes to your monthly electricity bill?

For those in Semenanjung Malaysia , TNB’s tariff is approximately 30 sen to 45 sen per kilowatt-hour (kWh), depending on your usage.


The more you use, the more expensive the rates!


Below is a short table of common electrical appliances, and a rough estimate on how much they cost to run for every hour.


(The cost may seem low, but remember, even using 3 sen/hour means that you will be paying about RM 20 a month if you leave it on for 24 hours a day!)
