Continuation of Exercises 1 and 2. (a) How much energy is stored in the magnetic field of the inductor one time constant after the battery has been connected? Compute, this both by integrating the expression and by using Eq (30.9). and compare the results. (b) Integrate the expression obtained to find the total energy supplied the battery during The time interval considered in part (a). (c) integrate the expression obtained in to find the, total energy dissipated in the resistance of the inductor during the, same time period. (d) Compare the results obtained in parts (a).(b), and (c).

Exercise 1

(a) What is the power input to the inductor from the battery as a function of time if the circuit is completed at t = 0? (b) What is the rate of dissipation of energy in the resistance of the inductor as a function of time? (c)What is the rate at which the energy of the magnetic field in the inductor is increasing, as a function of time? (d) Compare the results of parts (a), (b), and (c).

Exercise 2

In Fig switch S1 is closed while switch S2 is kept open. The inductance is L = 0.380 H, the resistance is R = 48.0 Ω, and the emf of the battery is 18.0 V At time t after S1 is closed, the current in the circuit is increasing at a rate of di/dt = 7.20 A/s. At this instant whal is Vab, the voltage across the resistor?
