Question
Write Joule's law.
✓
Answer
According to Joule's law, under proper conditions, work done on a system (W) and heat generated (H) are mutually proportional, that is
$W \propto H \Rightarrow W = JH$
Where J is the mechanical equivalent of heat.
$W \propto H \Rightarrow W = JH$
Where J is the mechanical equivalent of heat.
