In this circuit:
Assuming ideal diodes
We are required to calculate VD1, VD2, ID1, and ID2.
- If I assume that D1 is off and D2 is on which is a wrong assumption (as I think). How I prove that it is wrong? how to calculate Vx to show that D1 should be on here?
Edit: I calculated Vx as following:
I = (9 + 6) / (22k + 43k) = 2.31 * 10^-4
V(of 23k resistor) = 43k * 2.31 * 10^-4 = 9.93 v
=> Vx = 9.93 - 6 = 3.93 v
Is that correct?
- If I assume that D1 and D2 are both on, then the circuit will look like:
How can I calculate ID1 and ID2? Can this resulting circuit redrawn to be easier to solve?
