Question

In her bathroom, Mindy has an overhead heater that consists of a coiled wire made of nichrome that gets hot when turned on. The wire has a length of 3.5 m when it is uncoiled. The heating element is attached to the normal 120-V wiring and when the wire is glowing red hot it has a temperature of about 384

Explanation / Answer

A. P = V^2/R ==> Rhot = V^2/P O B. Ihot = V/Rhot A C. Rcold = Rhot*(1-k?T) O where ?T = 384 C R = ?L/A = ?L/(pd^2/4) ==> d = sqrt(4?L/(pRcold)) m D. Icold = V/Rcold A just put your values here its so simple dear
