A flat coil of wire has an inductance of 40.0 mH and a resistance of 5.90 Ω. It is connected to a 26.3-V battery at the instant t = 0. Consider the moment when the current is 2.90 A.
(a) At what rate is energy being delivered by the battery?
(b) What is the power being delivered to the resistance of the coil?
(c) At what rate is energy being stored in the magnetic field of the coil?
