1. A 0.245-H inductor and a 290 Ω resistor are connected in series to a 15.0-V battery. What is the maximum current that flows in the circuit?
2. How long after connecting the battery does the current reach half its maximum value?
3. When the current is half its maximum value, find the energy stored in the inductor.
4. When the current is half its maximum value, find the rate at which energy is being stored in the inductor.
5. When the current is half its maximum value, find the rate at which energy is dissipated in the resistor.
6. Now imagine, the same circuit: a 0.245-H inductor and a 290 Ω resistor are connected in series to a 15.0-V battery, but instead of being negligibly small, the internal resistances of the inductor and the battery are 78.5 and 23.0, respectively. What is the maximum current that flows in the circuit in this case?
7. And how long after connecting the battery does the current reach half its maximum value in this case?
