Question 24 1 pts A hair dryer advertises a power of 1600 W when used on a 120 Vac line. What is the current that the hair dryer uses (in A)?
The heating element in a hair dryer is essentially a wire whose resistance causes it to become red-hot when a current exisits in it. Such wires are usually made of nichrome (a nickel-chromium alloy), whose resistivity is p=1.0*10^-6 ohm*m. (a) Suppose one such wire has a diameter of 0.30 mm and a resistance of 9.0 ohm. What is the length of the wire? (Note that wires like this in a hair dyrer tend to be coiled around to save space)...
