A dual voltage/dual resistance AC hair dryer can be used with a 120 V or 230 V power supply. A switch allows the user to set the voltage (and hence the resistance) to the appropriate value. A tourist takes her 1530 W dual voltage hair dryer to Europe. She forgets to set the switch to 230 V. What power does the hair dryer consume before it starts to smoke?

W
