Hello,

I have been given a homework problem about ideal diodes. The diagram is below. I need to find V and I. I have the solution (4 mA and 1V) however I am unsure as to why it is so.

I would have set 5V at the node where the resistor and 3V diode meet therefore setting all the diodes to be reversed-bias. This is obviously wrong as the voltage at that node needs to be 1V to satisy the V and I answers.

Thank you.
