The current in a semiconductor diode is often measured by the Shockley equation

$=()$

Name:

where V is the voltage across the diode; I$0$ is the reverse current; a is a constant; and I is the resulting diode current.

If a $=5,$ I$0=106,$ and V is uniformly distributed over $(1,3).$ Find the following:

$1.\{>2\}$and$\{1\mathrm{.}5<<2\mathrm{.}5\}2.[]$ and $()$

$3.()$

$4.()$
