154899 Two different coils have self-inductance $L_{1}=8$ $\mathrm{mH}, \mathrm{L}_{2}=2 \mathrm{mH}$. The current in one coil is increased at a constant rate. The current in the second coil is also increased at the same rate. At a certain instant of time, the power given to the two coils is the same. At that time the current, the induced voltage and the energy stored in the first coil are $i_{1} V_{1}$, and $W_{1}$ respectively. Corresponding values for the second coil at the same instant are $i_{2}, V_{2}$, and $\mathrm{W}_{2}$ respectively.
154901 A uniform magnetic field $B$ points vertically up and is slowly changed in magnitude, but not in direction. The rate of change of the magnetic field is $\alpha$. A conducting ring of radius $r$ and resistance $R$ is held perpendicular to the magnetic field and is totally inside it. The induced current in the ring is then
