کرنٹ کو ایک سمت میں چلنے دیں، ٹو ٹرمینل ہے جسے کیتھوڈ اور اینوڈ کہتے ہیں، کرنٹ بہتا ہے، جب انوڈ پر مثبت وولٹیج اور کیتھوڈ پر منفی وولٹیج کا اطلاق ہوتا ہے تو مندرجہ ذیل میں سے کس ڈیوائس کی خصوصیت ہوتی ہے؟
Explanation

A diode allows current to flow in only one direction — from anode (positive) to cathode (negative).

It acts as a one-way valve for electric current, conducting only when forward-biased (positive to anode, negative to cathode).
