Physical Quantity Analogous to Inductance

In summary, there are analogies between physical quantities in electromagnetism and heat transfer, such as electric field to temperature gradient. However, there is no direct analogy between inductance and a physical quantity in heat transfer. In mechanics, the concept of inertia can be seen as an analogy, such as in the case of a paddle wheel in a flowing stream.

Hi,

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") ?

Regards,

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 …​

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

What is a physical quantity analogous to inductance?

The physical quantity analogous to inductance is capacitance. Both inductance and capacitance are components of electrical circuits and are measured in the unit of henries (H).

How is inductance different from capacitance?

Inductance is the measure of an object's ability to store energy in a magnetic field, while capacitance is the measure of an object's ability to store energy in an electric field. Inductors store energy in the form of a magnetic field, while capacitors store energy in the form of an electric field.

How does inductance affect an electrical circuit?

Inductance affects an electrical circuit by resisting changes in current flow. It causes a delay in the response of current to changes in voltage, and can also cause the current to continue flowing even after the voltage source is removed.

What are some examples of inductors?

Some common examples of inductors include the coils in electronic devices such as televisions, radios, and computers. Transformers, motors, and generators also use inductors to function.

Why is understanding inductance important in science?

Understanding inductance is important in science because it plays a crucial role in the functioning of electrical circuits. It is also important in the fields of electromagnetism and electronics, and is used in a wide range of technological applications.
