Would you help me with d and c? This is for my practice set. Thank you!
In the figure R1 When the switch is opened after having been closed for a long time, the current in the inductor drops from 1.00 A to 0.250 A in 0.200 s. What is the inductance of the inductor in mH? = 4.00 N , and R2 = 1.00 N. The inductor is ideal. %3D Şekildeki devrede R1 = 4.00 N , ve R2 = 1.00 N olarak verilmişlerdir. Solenoidin iç direnci yoktur. Anahtar uzun süre sonra kapalı kaldıktan sonra açılırsa solenoidden geçen akım 0,200 s içinde 1,00 A değerinden 0,250 A değerine düşmektedir.
