Determine whether the ideal diode is conducting.

VS$=15$V;VB$=7$V;R$1=6\backslash$Omega ;R$2=5\backslash$Omega $.$

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

For the open circuit assumption what is the current?

Question $3$

For the above problem with

VS$=12$V;VB$=7$V;R$1=6\backslash$Omega ;R$2=8\backslash$Omega $.$

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

Question $4$

Continued from previous question

Is the diode conducting?

Not Conducting

Conducting
