A 8.55 H inductor with negligible resistance is placed in series with a 14.9 V battery, a 3.00 Ω resistor, and a switch. The switch is closed at time t = 0 seconds.
(a) Calculate the initial current at t = 0 seconds.
(b) Calculate the current as time approaches infinity.
(c) Calculate the current at a time of 2.28 s.
(d) Determine how long it takes for the current to reach half of its maximum.
