🔬 Class 12 Physics Practical | Determination of Resistance Using Meter Bridge

Hello students!
Welcome to the Physics practical series by Shrine Vailankanni Senior Secondary School.
In today’s video, Ms. Princy Evangeline, Physics teacher for Grade 12, explains the second important Physics experiment — to find the resistance of a given wire using a meter bridge.

This video takes you step by step through the aim, apparatus, circuit diagram, procedure, observations, calculations and final result, with special focus on understanding the concept behind the experiment.

📌 Aim of the Experiment
To determine the resistance of a given wire using a Meter Bridge.

⚙️ Apparatus Used
• Meter Bridge
• Battery Eliminator
• Known Resistance Box
• One‑way Key
• Jaw Key
• Unknown Resistance (wire)
• Galvanometer
• Jockey
• Connecting Wires

🔌 What’s Covered in This Video
✔️ Meter bridge circuit diagram explanation
✔️ Proper circuit connections
✔️ Identifying null deflection using the galvanometer
✔️ How to take accurate readings
✔️ Tabulation of readings
✔️ Formula used:
  X = (100 − L) / L × R
✔️ Calculation of resistance
✔️ Finding the mean value
✔️ Final result of the experiment
✔️ Important precautions while using the jockey

📊 Result
The mean value obtained from the readings gives the final resistance of the given wire.

⚠️ Important Precaution
The jockey must be moved slowly and carefully to obtain a perfect null deflection, ensuring accurate readings.

🎓 This video is highly useful for Class 12 Physics practical exams and board exam preparation.
