Consider the circuit of Prob. 19.153 when the capacitor C is removed. If switch S is closed at time t = 0, determine
(a) the final value of the current in the circuit,
(b) the time t at which the current will have reached (1 2 1/e) times its final value. (The desired value of t is known as the time constant of the circuit.)
Prob. 19.153 Express in terms of L, C, and E the range of values of the resistance R for which oscillations will take place in the circuit shown when switch S is closed.
