A long metallic cylindrical rod of radius
, length
(
) and electrical resistivity
is kept in vacuum and is carrying an electric current of
. The only way it loses heat to the ambient is via radiation. If the ambient temperature is
, then the steady-state temperature of the rod is ________
.
(Round off to the nearest integer).Given: Stefan-Boltzmann constant =
Neglect the heat loss by the two flat ends of the rod and assume emissivity = 1.
