2. Mr. Lewis loves electronics so much, one night after having a cup of coffee he decided to make an RL circuit in which L = 4H and R = 100 is connected to a battery with e = 22 V at time t = 0. a) U = 0.5 J b) dU/dt = 7.5 J/s a. What energy is stored in the inductor when the current in the circuit is 500 mA? b. At what rate is energy being stored in the inductor when I = 2.5 A? c. What power is being delivered to the circuit by the battery when I = 500 mA? d. Mr. Lewis decided to make an air- core solenoid with 108 turns, 8 cm long and has a diameter of 1.2 cm. How much energy is stored in its magnetic field when it carries a current of 100 Ma? c) 11 W Please solve question part d) Thanks!
