A 2.4 Henry inductor is connected in series with a 12.0 Volt direct current battery, a 6.0 Ohm resistor, and a switch. The switch is open so no current is flowing in the circuit. Explain what happens to the current once the switch is closed. Intelligently use "Faraday's law" and "Lenz's law" and "time constant" in your explanation. Describe what a graph of current versus time would look like, what it's value would be at time = 0, and what its value would be after a very long time.
