Question
In the circuit below, a parallel combination of a 10.0-? resistor and a 7.0-mH inductor is connected in series with an R =3.5-? resistor, a 8.0-V dc battery, and a switch. After the switch has been closed for a very long time, it is opened.

(a) What is the voltage across the 3.5-? resistor immediately after the switch is opened?
(b) What is the voltage across the 10.0-? resistor immediately after the switch is opened?
Part (a) is 0V, but I don't know how to do part (b).
