A series RL circuit formed of a R = 1.20-ΩΩ resistor, a L = 11.0 H inductor, and connected to a V = 7.00 V battery. (a) What is the time constant for this circuit? (b) Once the switch is closed, how long (t) does it take the current to reach half its maximum value (Imax/2)?
Group of answer choices
9.2 s, 6.38 s
13.1 s, 5.9 s
11.2 s, 7.9 s
2.9 s, 8.33 s
An LR circuit is hooked up to a battery as shown in the figure, with the switch initially open. The resistance in the circuit is R=140 Ω, the inductance is L=2.20 H, and the battery maintains a voltage of E=48.0 V. At time t=0 the switch is closed.
a) What is the current through the circuit after the switch has been closed for t=6.91E-3 s?1.22×10-1 A
b) What is the voltage across the inductor after the switch has been closed for t= 6.91E-3 seconds?3.09×101 V
How much energy is stored in the inductor at t= 6.91E-3 seconds. What is the power dissipation in the resistor at t=6.91E-3 seconds?2.09 W
c) How much energy is stored in the inductor at t= 6.91E-3 seconds
1.64×10-2 J
d) How much work has the battery done from the time the switch was closed until t=6.91E-3 s?
e) How much energy has been dissipated in the resistor from the time the switch was closed until t= 6.91E-3 seconds?
(The answers in bold are answers for the previous questions. I need help with d and e)
(a) If an inductor carrying a 1.95 A current stores an energy of 0.250 mJ, what is its inductance? Answer in mH
(b) How much energy does the same inductor store if it carries a 3.1 A current? Answer in mJ
