A Nichrome wire is used as a heating element in a toaster. From the moment the toaster is first turned on to the moment the wire reaches it maximum temperature,the current in the wire drops by 20% from its initial value (the resistance is increased by 20%). What is the temperature change in the wire? The temperature coefficient for Nichrome is =0.0004(⁰C)^-1
