Question
A tungsten wire in a vacuum has length 15.0 cm and
radius 1.00 mm. A potential difference is applied across it.
(a) What is the resistance of the wire at 293 K? (b) Suppose
the wire reaches an equilibrium temperature such that it
emits 75.0 W in the form of
of any radiation from its environment, what is the temperature
of the wire? (Note: e = 0.320 for tungsten.) (c) What is
the resistance of the wire at the temperature found in part
(b)? Assume the temperature changes linearly over this temperature
range. (d) What voltage drop is required across the
wire? (e) Why are tungsten lightbulbs energetically inefficient
as light sources?
