The unit of self-inductance is
View answer and explanation
Correct option: C
Ohm second
Option C (Ohm second) is correct because self-inductance (L) is related to voltage (V) and rate of change of current (dI/dt) by V = L(dI/dt), so L = V/(dI/dt).

Statement-I: Random errors can be positive or negative.
Statement-II: Cause of random errors are uncertain. An object is moving through the liquid. The viscous damping force acting on it is proportional to the velocity. Then dimension of constant of proportionality is The error due to parallax is a: 2.34 is obtained by rounding of the number The dimensional formula of self-inductance is The dimension of is that of
