hi all need some help with this question I already calculated the values for (a), (b) and (d) need help with (c) and (e) thanks.
A circuit comprises an inductor of 9 H of negligible resistance connected in series with a 60Ω resistor and a 240Vd.c. source, Calculate:
(a) The time constant
(b) The current after 1time constant
(c) The time to develop maximum current
(d) The time for the current to reach 2.5A
(e) The initial rate of change of current.
