A coil has an inductance of 3 H and a wire resistance of 15 ohms. How long will it take for the current to reach its full value?

TC=L/R
5x TC=agreed to be essentially full value or steady state.

I agree with your tip, the time constant should be 0.2 seconds and it should be fully charged at 1.0 seconds. I answered 1 and got it wrong so I'm guessing the question is written for the time constant to be the answer (0.2)
