An inductor having self inductance L with its coil resistance R is connected accrodd a battery of emf E. When circuit is in steady state at t=0 an iron rod is inserted into the inductor due to which its inductance becomes nL(n>1).
Q1.After insertion of rod which of the following quantities will change with time?
1.Potential difference
2.inductance
3.Rate of heat production in coil
(a) only 1 (b) 1 and 3 (c)only 3 (d) 1,2 and 3
Q2.After insertion of rod,current in the circuit:
a)Increases with time
b)Decreases with time
c)Remains constant with time
d)First decreases with time then becomes constant
