Ethics is often concerned with determining the rules for developing and using technologies based on moral beliefs. Ethics thus emphasizes:
that conflicts based on beliefs are impossible to solve understanding
the reasons why certain technologies should or should not be created or developed.
requirements of the laws of a state or nation.
ways in which individuals can be excused from being held responsible for the negative impacts of technology.

Conductor
Convection
Rectification
Thermal
