Detailed Solution

Hair dryer works on the basis of the heating effect of current.
A hair dryer has an element of high resistance, and the element gets hot when an electric current passes through it. This is the heating effect of the electric current. The amount of heat produced is directly proportional to the square of current passing through the element and the resistance of the element. We have, H ∝ I2R, where H is the heat produced, I is the current and R is the element’s resistance.
