The current through a bulb is increased by $1 \%$. Assuming that the resistance of the filament remains unchanged the power of the bulb will

You are given two resistances $R_{1}$ and $R_{2} .$ By using them singly, in series and in parallel, you can obtain four resistances of $1.5\, \Omega, 2\, \Omega, 6\, \Omega$ and $8\, \Omega$. The values of $R_{1}$ and $R_{2}$ are

A rectangular coil of $100$ turns and size $0.1 \times 0.05\, m$ is placed perpendicular to a magnetic field of $0.1\, T$. The induced emf when the field drops to $0.05\, T$ in $0.05\, s$ is

A metallic rod of length $l$ is placed normal to the magnetic field $B$ and revolved in a circular path about one of the ends with angular frequency $\omega$. The potential difference across the ends will be :
