a: temperature ~
b: voltage


"There is also an electrical analog which may help - temperature is like voltage; heat is like amperage.

Or a fluid analog - temperature is like pressure; heat is like flow.

Heat was originally believed to be a fluid, flowing from high temperature material to low temperature material. This fluid idea is incorrect, as they later realized. However, it may help somewhat to use the idea for basic purposes."
