$Df=0\mathrm{.}7V($ for $1N4148)$

Find the nodal voltages of node $A,B,$ and $C.$

Discuss how the following nodal voltages change with the resistor values:

V$\_$A with respect to $RI$

$V_{-}B$ with respect io $R2$

V$\_$C with respect to R$3$

$($Provide comments on the impact of increasing or decreasing each resistor value on the corresponding nodal voltage.$)$
