# Solution: An inductor with an inductance of L = 6.0 H and a resistor with resistance R = 10 Ω are connected in series to the terminals of a battery with EMF = 20 V and negligible internal resistance. There is a switch inserted in the circuit in line between battery and the inductor: Find the current 0.015 seconds after the switch is closed.
