How is power rating related to energy consumption?
The larger the power rating in the electrical appliance, the more energy is used every second. The longer the usage time, the more electrical energy is consumed. Table shows the power rating and operating voltage of some household electrical appliances.
What kind of appliances have a high power rating?
Appliances that have a heating effect such as electric ovens and electric kettles usually have a high power rating and consume more electricity. The National Electricity Board (Tenaga Nasional Berhad) calculates the electricity bill according to the readings of the kilowatt-hour meter as shown in Figure.
Which is the correct equation for electric power?
Power is the rate at which energy is moved, and so electric power is. P = P E t = qV t P = P E t = q V t. Recognizing that current is I = q / t (note that Δ t = t here), the expression for power becomes. Electric power ( P) is simply the product of current times voltage. Power has familiar units of watts.
Are there any electrical appliances that are energy efficient?
Most of the electrical appliances manufactured today are of high efficiency. It is a good practice to buy an energy-efficient unit to replace an old one.
