PN Junction Diode Practical Explained | Forward & Reverse Bias | CBSE Class 12 Physics
PN Junction Diode is one of the most important experiments in CBSE Class 12 Physics practical examinations.
In this video, Dr. Puneet Kr explains the PN Junction Diode experiment step by step, covering both forward bias and reverse bias characteristics, exactly as expected in board practicals.
This video covers:
• Identification of P and N sides of diode
• Forward bias circuit connections explained clearly
• Role of ammeter and voltmeter
• Why correct battery range is important
• How current increases with voltage in forward bias
• Understanding knee voltage
• Reverse bias circuit connections
• How breakdown voltage occurs
• How to draw I–V characteristic graphs
• Common mistakes students make in this practical
• Viva-important points for exam
This video is extremely useful for:
• CBSE Class 12 board practicals
• External practical exams
• Viva preparation
• Pre-board practical revision
📌 Watch this video before your practical exam for full confidence.
