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?
