1. A hair dryer has a power rating of 1700 W at 110 V rms. Assume the hair dryer circuit contains only resistance. 2. The peak voltage is sqrt2 * rms voltage. 3. I got my esistance of the heating element is 7.12ohm and the rms current drawn by the hair dryer is 15.45A. But I am not sure how to get the maximum instantaneous power.
