Tungsten has a temperature coefficient of resistivity of 0.0045 (C°)-1. A tungsten wire is connected to a source of constant voltage via a switch. At the instant the switch is closed, the temperature of the wire is 28 °C, and the initial power delivered to the wire is P0. At what wire temperature will the power that is delivered to the wire be decreased to 1/2 P0?
