   Two identical inductors are connected in two different configurations $P$ and $Q$, where a time varying current $I(t)$ is flowing, as shown in the figure. The induced emf between points $a$ and $b$ for configuration $P$ is $E_P$ and that for configuration $Q$ is $E_Q$. The ratio $E_P/E_Q$ is: [Neglect the effect of mutual inductance.] Figure: in $P$ the two inductors are in series, with $a$ at the top end of the upper inductor and $b$ at the junction between the two inductors. In $Q$ the two inductors are connected in parallel, with $a$ at the common top junction and $b$ at the common bottom junction.

   A conducting loop of finite resistance lies on the $x - y$ plane. There is a constant magnetic field in the $z$ direction. The area of the loop varies with time $t$, as $A = A_0(1 + \sin t)$ in appropriate units. The figure that correctly indicates the qualitative behaviour of the power $P$ dissipated in the loop as a function of time is: Each option is a graph of $P$ against $t$.
