Which mechanism causes current regulation in a Zener diode?

💡 Explanation

The current regulation exhibited by a Zener diode happens because the avalanche breakdown effect allows the diode to maintain a nearly constant voltage across it, therefore voltage is controlled rather than current variation due to varying voltage levels.
