Question

1 Pluiem. we higure at the right for problems 1 and 2 [6] 1. A 5.61 m2 resistor, 1.55 H inductor EMF source E = 9.50 V. How much energy a resistor, 1.55 Hinductor and switch are connected in series across an idea 9.50 V. How much energy is stored in the magnetic field of the inductor when switch S is closed and the magnetic field becomes stable wer: (a) 1.88 J. (b) 2.22J (c)2.77J. (d) 3.20 J. (e) 3.79). (1) Wer: (a) c h energy is stored in are connected in serie witch S is clos [6] 2. In the previous problem, Answer: (a) 1.38 ms. (b) 1.85 ms. S ous problem, how long after switch S is closed until the magnetic field is stable? 1.38 ms. (b) 1.85 ms. (c) 2.33 ms. (d) 2.79 ms. (e) 3.41 ms. (1) (C) 2.3 m 1813 An

Answer 1

Sono DD 2.221 at steady state current in RL cúrait - I = 5 / 2 350 r = 1693.40 A Energy Stored (El=ILI 2 = 1 / 2 (lissau GH) (1693-40A)? E = 2,2811 ☺ @ 1038 ms Time required to stable (t) = 5€ = 5(1/2) =5(lossy5bH) 5.60 x103 r = 1.38x15²s - 1.38 ms
