35.0\text{ V}

battery with negligible internal resistance, a

50.0\,\Omega

resistor, and a

1.25\text{ mH}

inductor with negligible resistance are connected in series with an open switch. The switch is suddenly closed. (1) How long after closing the switch will the current through the inductor reach one-half of its maximum value? (2) How long after closing the switch will the energy stored in the inductor reach one-half of its maximum value?
