Hello , i was asked to find ''the Initial rate of growth of the current'' but am not quiet sure how do i do that ,

Full questions:

A coil having a resistance of 33ohms and an inductance of 3.3H is connected across a 100v dc supply.

So i used Ltspice to find it ,but am not sure what measurement i need to take .

Edit:i came up with (e/33)*(1-e^(-2/(3.3/33))) = 0.0823721764501894 , is that right ?
