In the circuit shown in the figure, the inductor has inductance L = 2.50 H and negligible internal resistance. The battery has a voltage of V½ = 11.0 V and is connected in series to a resistor of resistance Rj = 15.0 N. A second resistor has a resistance of R2 L R2 = 185 N. R, The switch S has been closed for a long time. At time 1 = 0, the switch is opened.

Please help with the 6 questions:
In the circuit shown in the figure, the inductor has inductance ?=2.50 HL=2.50 H and negligible internal resistance. The battery has a voltage of ?b=11.0 VVb=11.0 V and is connected in series to a resistor of resistance ?1=15.0 Ω.R1=15.0 Ω. A second resistor has a resistance of ?2=185 Ω.R2=185 Ω.
The switch ?S has been closed for a long time. At time ?=0,t=0, the switch is opened.
What is the current ?b,0Ib,0 in the battery, the current ?2,0I2,0 in resistor ?2,R2, and the current ?L,0IL,0 in the inductor at ?=0.t=0.
What is the current ?b,∞Ib,∞ in the battery, the current ?2,∞I2,∞ in resistor ?2,R2, and the current ?L,∞IL,∞ in the inductor after the switch is opened for a long time (i.e., ?=∞).
