154879 Three solenoid coils of same dimension, same number of turns and same number of layers of winding are taken. Coil 1 with inductance $L_{1}$ was wound using a Mn wire of resistance $11 \Omega / \mathrm{m}$; coil 2 with inductance $L_{2}$ was wound using the similar wire but the direction of winding was reversed in each layer;Coil 3 with inductance $L_{3}$ was wound using a superconducting wire. The self inductance of the coils $L_{1}, L_{2}, L_{3}$ are

154880 If the coefficient of mutual induction of the primary and secondary coils of an induction coil is $5 \mathrm{H}$ and a current of $10 \mathrm{~A}$ is cut off in $5 \times 10^{-4}$ second, the emf induced (in volt) in the secondary coil is

154881 There are two solenoids of same length and inductance $L$ but their diameters differ to extent that one can just fit into the other. They are connected in three different ways in series. 1) They are connected in series but separated by large distance 2) they connected in series with one inside the other and senses of the turns coinciding 3) both are connected in series with one inside the other with senses of the turns opposite as depicted in figures 1,2 and 3 respectively. The total inductance of the solenoids in each of the case 1,2 and 3 are respectively
