A solenoid has an inductance of 60 henrys and a resistance of 30 ohms. If it is connected to a 100 volt battery. How long will it take for the current to reach (e-1)/(e)~=63.2% of its final value

RL circuit, current during the transition A solenoid has an inductance of 53 mH and a resistance of 0.37 Omega . If the solenoid is connected to a battery, how long will the current take to reach half its final equilibrium value? (This is a real solenoid because we are considering its small, but nonzero, internal resistance.)
