Electrical Knowledge: Did You Know ??

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!)
