[a]1. The problem statement, all variables and given/known data[/b] I have the following circuit attached as PDF and I need to find out if the state of the diode and what V0 is. The forward voltage on the diode is 1V. [a]3. The attempt at a solution[/b] I just simply used current division to know that the diode is on since 1V travels up to the diode and 1V through the 1KΩ resistor. But at V0 what do I do? I would stupidly say it's zero since it's an open circuit but I am way to new at this.
