The article examines the issues associated with the analysis of the hot cathode heating
process using the law of conservation of energy. We conducted the simulation of the hot
cathode heating process using a thin rod, heated by electric current. The heating process
is described by the differential equation in partial derivatives of the second order, and its
output is based on the regularities of the thermal conductivity of solid bodies, the theory
of thermal conductivity and the well-known mathematical apparatus by means of com-
puters.
Keywords:
hot cathode, heating process, thermal conductivity, software model,
MathCad.
