The temperature dependence of resistance is also quantified by the relation R2=R1[ 1+(T2T1) ] where R1 and R2 are the resistances at temperatures T1 and T2, respectively, and is known as the temperature coefficient of resistance. If a copper wire has a resistance of 55 at 20C, find the maximum permissible operating temperature of the wire if its resistance is to increase by at most 20. Take the temperature coefficient at 20C to be =0.00382.
