An inductor with an inductance of 2.60H and a resistor with a resistance of 14.0ohms are connected to the terminals of a battery with an emf of 7.00V and negligible internal resistance.
1. Find the initial rate of increase of the current in the circuit.
2. Find the initial potential difference across the inductor.
3. Find the current 0.186s after the circuit is closed.
4. Find the maximum current.
