A 45 V battery with negligible internalresistance, a 50 Ωresistor and a 1.0-mH inductor with negligible resistanceareconnected in series with an open switch. The switch is closedatt=0.
(a) What is the maximum current in the circuit and when doesitoccur? (Ans: 0.90 A ,after a long time) (b) What is the maximum energy stored in theinductor? (Ans:4.1x10^-4 J) (c) At what time t will the current reach one-half ofits maximum value? (Ans: 1.4x10^ -5 s)
