Question

When a certain circuit consisting of a constant emf. E, an inductance L and a resistance R is closed , the current in it increases with time according to curve 1. After one parameter (E, Lor R) is changed , the increase in current follows curve 2, when the circuit is closed second time. Which parameter was changed and in what direction:-
