Unformatted text preview: 1 . [1 point, 10 tries] Consider the circuit in the figure below, taking E = 6 V, L = 7.77 mH, and R = 4.39 . What is the inductive time constant of the circuit? Answer: 1.77E-03 s 1 2 . [1 point, 10 tries] Calculate the current in the circuit 296 s after the switch is closed. Answer: 2.10E-01 A 1 3 . [1 point, 10 tries] What is the value of the final steady-state current? Answer: 1.37E+00 A 1 4 . [1 point, 10 tries] How long does it take the current to reach 79.5% of its maximum value? Answer: 2.80E+00 ms 1 5 . [1 point, 10 tries] An inductor that has an inductance of 14.9H and a resistance of 37.9 Ohms is connected across a 123.7V battery. What is the rate of increase of the current at t=0? Answer: 8.30e+00 A/s 1 6 . [1 point, 10 tries] Calculate the energy associated with the magnetic field of a 248 turn solenoid in which a current of 2.15A produces a flux of 3.6210-4 Tm 2 in each turn. Answer: 9.65e-02 J 1 7 . [1 point, 10 tries] In the figure below, take E = 6 V, R 1 = 4.92 , and R 2 = 1.23 . The inductor has negligible resistance. When the switch is thrown open after having been closed for a long time, the current in the inductor drops to 0.248 A in 0.167 s. What is the inductance of the inductor?...
