Hi Students! The practical examinations are accompanied by viva voce by the external/internal examiner to ensure the genuineness of their work and to analyse the understanding of the subject by the students. So it is important to prove yourself by performing well in the viva voce. The following questions will be of some help to prepare well for…… Continue reading Class XI Physics Practical Exam Viva Voce
Hello students! It’s the time of AISSCE Practical Examination. How was your Physics Practical Examination and Viva? Which questions were asked to you? Which were the experiments and activities you were asked to perform? How farely did you do it? Share your experience here as comments to this post. Your responses will be a boon…… Continue reading How was your Physics Practical Examination?
State the Principle of a potentiometer. (The students say that potential drop is proportional to length but the constant quantities are not mentioned) How can we increase the sensitivity of a potentiometer? Define figure of merit of a galvanometer. Which has more resistance – a galvanometer or a milliammeter? How does an LED emit light?…… Continue reading Random collection of Physics Viva Questions

(Assuming that the student was assigned the experiment “To determine the internal resistance of a cell using potentiometer”) Examiner (E): What was the experiment allotted to you? Students(S): Sir, I was assigned the experiment to determine the internal resistance of a primary cell using potentiometer. E: OK, Tell me the principle of a potentiometer S:…… Continue reading An Exemplary Viva Voce (CBSE Class XII Physics Practical)
Viva Voce is one one of the important factor which decides your overall score in Physics Practical examination. The external examiner is not knowing what you are really. Viva Voce is the only means to have a direct interaction with you. Therefore your performance in viva has a direct impact on the marks you get…… Continue reading CBSE Physics Classs XII Viva Voce – Tips to perform well
Shalini asked: How to do calculation in the physics practical(capillary rise method)..how to measure the diameter of the capillary tube? A Travelling Microscope A travelling microscope is used to determine small distance to an accuracy of 0.001 cm. The measurement principle is based on the principle of vernier. In a typical travelling microscope, the main…… Continue reading Physics Practical:: Measurement of diameter of capillary tube using travelling microscope.
