When an electric heater is turned on, the Nichrorne heating element is at 0 C and draws a current of 14 A, with a potential difference of 120 V between the ends of the element. The element heats up to 864 C, with the potential difference constant. Find the nal current. (The temperature coefficient of resistivity of Nichrome is 4.0 x 10"1 (C)'1.) l:l
