Question

What are fluxes? How are they useful?

Answer 1

Hint: We can describe the electric flux over a surface using Gauss law.
The Gauss law is also used to describe the coulomb law
The SI unit of electric flux is volt meters

Complete answer:
The electric flux is the overall field coming from the surface by the usage of the gauss divergence.
We cannot use the capacitor for explicit energy storage even if it is capable of storing energy. The capacitors are like temporary energy storage devices. And they are very commonly used in circuits.
The photo copying machine applications the electric flux is used the cleaning applications like air purifier which uses the electric flux.
Also, industrial electrostatic precipitators are one of the applications of electric flux.
We applied the electric flux in our day-to-day life, to produce the voltage the generator mostly used.
And some other uses of the electric flux is given below,
The measure of the electric field through the particular area is known as the flux.
The car alternator, the electric train motor, the radio tuning circuit, the electrical impulses in our brain, the water pressure on the tap. Everything in the world cannot work without the electric flux which is described in the Maxwell equation.

Note:
We can obtain more charge when we have more electric flux here; these charges help to produce the electric field lines.
Generally, the electric flux is directly proportional to the electric field lines which are perpendicular to the surface.
The flux is known as the vector field.
