But L/R is the time constant of R-L circuit. So option [C] should be correct.

What is the expression for the amplitude?

Jagat said: (Aug 21, 2012)  
Yes.. T = L / R. Option C is correct..

Quality factor = L/R.

So option D is correct.

How? explain me.

Here, Q=XL/R
Tc=L/R.

It's a low pass filter or circuit.

So, time constant t=L/R.
