What is the resistance of the dryer

Reference no: EM13248832

When operated on a household 110-V line, typical hair dryers draw about 1650 W of power. We can model the current as a long straight wire in the handle. During use, the current is about 3.0 cm from the user's head.

(a) What is the current in the dryer?

(b) What is the resistance of the dryer?

(c) What magnetic field does the dryer produce at the user's head? Compare the field with Earth's magnetic field to decide if we should have health concerns about the magnetic field created when using a hair dryer.
