Once the switch S is closed in Figure, the time required for the current to reach any
Question:
Once the switch S is closed in Figure, the time required for the current to reach any obtainable value depends, in part, oil the value of resistance R. Suppose the emf ξ of the ideal battery is 12 V and the inductance of the ideal (resistanceless) inductor is 18 mH. How much time is needed for the current to reach 2.00 A if R is
(a) 1.00??,
(b) 5.00 ??, and
(c) 6.00???
(d) For what value of R is the time required for the current to reach 2.00A least?
(e) What is that least time?
