# Does this circuit convert sinewaves to square waves?

As part of a graded assignment on diodes, I was given this question. I ended up designing this circuit :- simulate this circuit – Schematic created using CircuitLab

However, I only got partial credit for the circuit. The official solution was :- With each of the zener diodes having a breakdown voltage of $$\2.5\,\text{V}\$$. I want to ask before I challenge the grading. Will my circuit also work?

• "There also is a resistor in series with the sources which isnt shown" - Why isn't it shown? You drew a circuit (+1) but then you didn't supply the whole circuit, which contains very relevant information to your question? (-1) – Arsenal Apr 9 at 12:35
• Edited the circuit to add the resistor.I am sorry it wasn't there before, I forgot to add it while drawing and didn't know how to edit. – Mall Apr 9 at 14:49

Since the diodes used in your problem are ideal, you can consider them as short in forward bias and as voltage drop of $$\ 5 \, \text{V}\$$ in reverse bias.
So I think you should remove the voltage drop you made, replace it with a short circuit and the circuit will work but you should notice that it will produce square wave which has value of $$\5\,\text{V}\$$ in the first half cycle and value of $$\-5\, \text{V}\$$ in the second half cycle.
