What angle we take between magnetic field and plane of loop....discuss the cases when induced emf is zero in a rotating frame.Ans) We know that Magnetic Flux through a given area is given as ?=B.A= BAcosθLet θ=wt, where w is frequency of sourceNow, the Induced emf will be zero if:1. Magnetic field B is zero,2. Area of the conductor is zero.3. Angle between Magnetic field and Area Vector is 90oAlso the angle between the Magnetic field and plane of loop is taken as anticlockwise angle or positive angle
The rate of change of angular velocity with related to time is known as angular acceleration.
It is an instrument used to view pure spectrum. It makes dispersion without deviation with the help of n crown prisms and (n - 1½ flint prisms alternately arranged in a tabular str
Working: When plate potential (V p ) is positive, plate current ( I p ) flows in the circuit (because some emitted electrons reach to plate). If + V p enhances I p also increas
