An RL circuit is comprised of an emf source with E = 22V , resistance R = 150, and inductor L = 0.5H 1. What is the inductive time constant? 2. What is the maximum value of the current? How long does it take to reach 90% of this value? How many time constants is this? 3. After a long enough time for the current to reach its peak, the battery is disconnected without breaking the circuit. How long does it take to reach 1% of the maximum current? How many time constants is this
