In a $P-N$ junction,avalanche current flows in the circuit when the biasing is:

Which of the following graphs is correct for a $P-N$ junction? (When the $P-N$ junction is forward biased.)

The magnitude of the diffusion current in a $p-n$ junction is smaller than the magnitude of the drift current:

Which of the following is correct with respect to the following statements? Due to diffusion of electrons from $n$ to $p$-side:
$I$. electrons are accumulated in the depletion region.
$II$. electron drift current is from $p$-side to $n$-side.
$III$. an ionised donor is left in the $n$-region.
$IV$. electrons of $n$-side come to $p$-side and electron-hole combination takes place in $p$-side.
Select the correct option from the following.
