At what wire temperature will the power delivered

Reference no: EM13714149

Problem: 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 20 °C, and the initial power delivered to the wire is P0.

Part A: At what wire temperature will the power that is delivered to the wire be decreased to 2/3 P0?

°C

I need expert help to solve the above problem.
