 [A]. counter emf value [B]. induced voltage amplitude [C]. rise or decay time constant [D]. quality factor of the coil

Explanation:

No answer description available for this question.

 Prakhar said: (Dec 30, 2011) But L/R is the time constant of R-L circuit. So option [C] should be correct.

 Himanshu said: (Aug 20, 2012) What is the expression for the amplitude?

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

 Navdeep said: (Jul 31, 2013) What is the correct answer?

 Vinodkumar said: (Aug 20, 2013) But L/R is the time constant of R-L circuit. So option [C] should be correct.

 Aryaan said: (Jun 2, 2016) Quality factor = L/R. So option D is correct.

 Arun said: (Sep 22, 2016) How? explain me.

 Dlsingh said: (Jan 31, 2018) Here, Q=XL/R Tc=L/R.

 Raj Kumar M said: (May 13, 2020) It's a low pass filter or circuit. So, time constant t=L/R.
