- What is the current flowing through the battery immediately after the switch is closed and through the battery a long time after the switch has been closed? Use the following data: EMF = 14.5 V, R1 = 90.0 Ω, R2 = 10.0 Ω, L = 28.0 mH.The oscillating current in an electrical circuit is as follows, where I is measured in amperes and t is measured in seconds.
