1. A current in an RL circuit rises to one half of its maximum value in 7.0s. a) what is the inductive time constant for the circuit? b) if L= 0.8 H, what is the value of the resistance?
2. My book says the (time constant) = L/R
3. I've tried plugging into the above equation, but I know there's something missing, and I don't know what it is.
