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: Sir. The principle of a potentiometer is that the potential drop across any length of a wire of uniform cross section and composition and carrying a constant current is directly proportional to the length.
E: Good. What is internal resistance?

S: The resistance offered by the electrodes and electrolyte of a ....etc

physics practical viva questions for bsc

Q.1: Define surface tension?
Ans. The tangential cohesive force acting along the unit length of the surface of a liquid
T = F / L
Where F = total force along a line
L = length of the line
In this experiment:
F = m g = weight of the pan + weight in the pan.
L = 2 (length of the slide) + 2 (breadth of the slide).
Sometime we neglect the breadth since it is very small.

Q.2: What are units of surface tension in C.G.S. and S.I. (M.K.S.) system?
Ans. Dynes / cm (C.G.S.)
Newton / meter (M.K.S.)

Q.3: What ....etc
