In a \( p-n \) junction, the current I can be
\[
I=I_{0}\left[e^{\frac{e \mathrm{~V}}{k \mathrm{~T}}}-1\right],
\]
where \( I_{0} \) is called the reverse saturation current, \( V \) the voltage across the diode and is positive for forward bias and negative for reverse bias and \( I \) is the current through. the diode, \( k \) is the Boltzmann's constant \( \left(8.6 \times 10^{-5} \mathrm{eV}\right. \) \( -\mathrm{K}^{-1} \) ) and \( \mathrm{T} \) is the absolute temperature. If for a diode,. \( I_{0}=5 \times 10^{-12} \mathrm{~A} \) and \( T=300 \mathrm{~K} \), then
what will be the increase in the current, if the voltage across the diode is increased to \( 0.7 \mathrm{~V} \) ?
