Question $2$

Determine whether the ideal diode is conducting.

VS$=12$V;VB$=5$V;R$1=5\backslash$Omega ;R$2=7\backslash$Omega

$1.$Assume closed $($open circuit$)$

For the open circuit assumption what is the current?

Question $3$

For the above problem with

VS$=11$V;VB$=7$V;R$1=10\backslash$Omega ;R$2=6\backslash$Omega $.$

What is the voltage at node $1($v$1)?$

Question $4$

Continued from previous question

Is the diode conducting?
