What is stephan's Boltzmann constant?

$\huge\blue{\underline{\underline{\bf Answer:-}}}$

Before going to stephan boltzmann constant let's understand the following law...

• Stephan Boltzmann Law

The energy of thermal radiation emitted per unit time by a blackbody of surface area A is given by

$u = e \sigma a {t}^{4}$

Where,

$\\ \\ \sigma \: \: is \: \: stephan \: \: boltzmann \: \: constant \\ \\ its \: \: value \: \: is \: \: \huge\red{\sigma = 5.67 \times {10}^{ (- 8)}}$
