A 140-mH inductor and a 4.80-N resistor are connected with a switch to a 6.00-V battery as shown in the figure below. We R L (a) After the switch is first thrown to a (connecting the battery), what time interval elapses before the current reaches 220 mA? ms (b) What is the current in the inductor 10.0 s after the switch is closed? A (c) Now the switch is quickly thrown from a to b. What time interval elapses before the current in the inductor falls to 160 mA? ms
