. A uniformly wound solenoidal coil of self inductance 1.8 x 10^-4 henry and resistance 6 ohm is broken up into two identical coils. These identical coils are then connected in parallel across  a 15-volt battery of negligible resistance. The time constant for the current in the circuit is …….. seconds and the steady state current through the battery is ……… amperes.

AB is a current carrying conductor in the plane of the paper as shown in the figure below. (i) What is the direction of the magnetic field produced by it at point ‘X’? Write the statement of the rule used to find the direction of field lines. (ii) If the polarity of the battery connected to the wire is reversed, how would the direction of the magnetic field be changed? (iii) Point ‘X’ is at a distance r1 and point ‘Y’ is at a distance r2 (r1
