Find CBSE Class 12 Physics Practice Paper (Set-II). This paper contains important questions from 2nd unit (Current electricity) of physics. These questions will not only help the students to prepare for exams in a better manner, but will also help them in understanding the depth with which a topic should be studied.

Few sample questions from the Question Paper are given below:

Q. Define the term ‘temperature coefficient of resistivity’. Draw a graph showing the variation of resistivity with temperature with temperature copper.

Q. Resistivity of the material of a conductor of uniform cross-section varies along its length as. Find its resistance if its length is L and area of cross section is A.

Q. You are given ‘n’ resistors, each of resistance ‘r’. These are first connected to get minimum possible resistance. In the second case, these are again connected differently to get maximum possible resistance. Compute the ratio between the minimum and maximum values of resistance so obtained.

Q. In a potentiometer arrangement, a cell of e.m.f. 1.25 V gives a balance point at 35.0 cm length of the wire. If the cell is replaced by another cell and the balance point shifts to 63.0 cm, what is the e.m.f. of the second cell?
