Practising the diagrams is necessary to get good marks. The aim of every student must be to score the maximum marks and not to lose even a single mark through silly carelessness. So, it is important to practice well to draw the diagrams as per the NCERT text book.
We are planning to publish a series of posts for all the diagrams as may be required for the AISSCE Class Xii Physics examination. You can view these online or may download and take a print.
Wish you all the best.
