Concept of Drift velocity and Relaxation time

Consider a metallic conductor contains a large number of free electrons which are moving randomly in all directions. Let such electrons are marked as 1,2,...n which are moving with random velocitie...

Rotational Mechanics

Rotational Mechanics is all about applying Newton's Law from the rotational frame of reference.

What might this be? (Hint: Unexplained Astronomical object)

Why are the divisions marked on the scale of an AC ammeter not equally spaced?

The A.C. ammeter works on the heating effect of the electric current. The heat produced by the electric current is directly proportional to the square of the current. Hence the divisions marked on the scale of our AC ammeter are not equally spaced. In order to have equally spaced scales, the variation should be linear or heat should be directly proportional to current, which is not the case.
