Embibe Experts Solutions for Chapter: Electromagnetic Induction and Alternating Currents, Exercise 2: Level 2

A long conductor $AB$ lies along the axis of a circular loop of radius $R$. If the current in the conductor $AB$ varies at the rate of $I$ ampere/second, then the induced emf in the loop is

For the given circuit, comment on the type of transformer used :

A transformer is employed to

An $LCR$ series circuit is connected to a source of alternating current. At resonance, the applied voltage and the current flowing through the circuit will have a phase difference of-

Figure shows a square loop of side $0.5 \mathrm{m}$ and resistance $10\mathrm{\Omega }$. The magnetic field on left side of line PQ has a magnitude $B=1.0 \mathrm{T}$. The work done in pulling the loop out of the field uniformly in $2.0 \mathrm{s}$ is
