Описание: 🔥 Class 12 Physics Current Electricity PYQ | Heat Produced & Potential Difference | CBSE 2017

In this video, we solve an important Class 12 Physics Previous Year Question (PYQ) from Current Electricity Chapter 3. This question is based on Joule’s law of heating and explains how heat produced per second changes with applied potential difference — a very common concept asked in CBSE board exams.

📘 Question [CBSE 2017]
The potential difference applied across a given resistor is altered so that the heat produced per second increases by a factor of 9. By what factor does the applied potential difference change?

You will learn:
Relation between heat and potential difference
Application of Joule’s Law
Step-by-step numerical solving
Board-exam oriented explanation
This question is extremely important for CBSE Class 12 Physics Board Exam, NEET and JEE mains revision.
