The statement is true because power is defined as the rate at which energy is transferred or converted. This means that if an appliance has a higher power rating, it is capable of transferring more energy within the same time frame compared to an appliance with a lower power rating.

For instance, if you have a 1000-watt kettle and a 2000-watt kettle, the 2000-watt kettle will transfer energy and boil water more quickly than the 1000-watt kettle because it has a higher power rating. This principle applies universally across electrical appliances, meaning that regardless of the type of appliance, a higher power rating inherently indicates that more energy is being transferred in the same amount of time. Thus, the correct understanding of how power relates to energy transfer supports the accuracy of the original statement.
