An inductor with an inductance of 2.70H and a resistance of 7.20(phi) is connected to the terminals of a battery with an emf of 5.80V and negligible internal resistance.
1) Find the initial rate of increase of current in the circuit.
2) Find the rate of increase of current at the instant when the current is 0.500A.
3) Find the current 0.300 after the circuit is closed.
4) Find the final steady-state current.
