Response Details:

V_T is the thermal voltage and at room temperature(300K) its value is around 25mV

$V_T = { kT \over q },$
where q is the magnitude of the electrical charge on the electron with a value 1.602 176 487(40) × 10⁻¹⁹ C. In electronvolts, the Boltzmann constant is 8.617 343(15) × 10⁻⁵ eV/K,
