Physical Quantity Analogous to Inductance

  1. May 12, 2013 #1

    I understand that some physical quantities in electromagnetism are analogous to physical quantities in heat transfer. For instance, electric field is analogous to temperature gradient.

    I want to know which physical quantity in heat transfer is analogous to Inductance ("L") ?

    welcome to pf!

    hi tapan_ydv! welcome to pf! :smile:

    i don't know about a heat transfer analogy,

    but a hydraulics analogy is a paddle-wheel

    A heavy paddle wheel placed in the current. The mass of the wheel and the size of the blades restrict the water's ability to rapidly change its rate of flow (current) through the wheel due to the effects of inertia, but, given time, a constant flowing stream will pass mostly unimpeded through the wheel, as it turns at the same speed as the water flow …​

    In mechanics.....inertia

    Reluctance to change...as in a paddle wheel.
