Analysis by assumed diode states

Click For Summary
SUMMARY

The discussion focuses on analyzing diode states in electrical circuits, specifically how to approach problems involving multiple diodes. Participants suggest starting by calculating the voltage across each resistor and assuming the states of the diodes based on the largest voltage differences. This method allows for systematic verification of each diode's state, ensuring a logical progression through the circuit analysis.

Homework Statement



I'm having a hard time trying to figure out where to start. I know I have to assume the diode states and then calculate if the assumptions work within the circuit.

The Attempt at a Solution



None as yet because I'm never sure where to start on these circuits when they are drawn in this way. Could someone give me a nudge in the right direction, or a general approach to these problems?

Thanks

Start by calculating the voltage across each resistor.
 
In addition to skeptic2's hint, I'd be inclined to start by assuming that only the 2 diodes with the biggest voltage difference between them are on, calculate the middle node's voltage, and then go to the next highest voltage difference diode and see if it is on, and so on...
