Question

The electric field profile in the depletion region of a p-n junction in equilibrium is shown in the figure. Which one of the following statements NOT TRUE?

Answer 1

Ans : (c)

Built in potential
${\Psi }_0=\frac{1}{2}\times \left({10}^{6}V/m\right)\times (1.1\times {10}^{-6}m)$
$=0.55Volts$ =550mVolts
But in question (option (c)) is given as $700mV$
