A transformer is used by a European traveler while she is visiting the United States. She primarily uses it to run a 1250-watt hair dryer she brought with her. When the hair dryer is plugged in to her hotel room outlet in Los Angeles, she notices that it runs exactly as it does at home. The input voltage and current are 120 V and 11.0 A, respectively.

What is the rate at which heat is generated in the transformer itself?

=_______ (W)
