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?
