An ideal Zener diode with breakdown voltage of –3 V is reverse biased with a negative input voltage Vi=−5V_i = -5 V. The magnitude of voltage difference between point B and A is:
[IMAGE]

Show answer and solution
<image_2>
∣Vinput∣(5 V)>∣Vzener∣(3 V)|V_{\text{input}}|(5~V) > |V_{\text{zener}}|(3~V)
Vzener=3 VV_{\text{zener}} = 3~V
VTotal=5 VV_{\text{Total}} = 5~V
∴∣VBA∣=(5−3)=2 V\therefore |V_{BA}| = (5-3) = 2~V
