In the figure on the right the resistances are each $75,L=0\mathrm{.}1H,$ and $E=90V.$ Find th

current through the upper resistor $R_1$ immediately after the switch is closed at

A$)0A$

B$)2\mathrm{.}4A$

C$)1\mathrm{.}2A$

D$)0\mathrm{.}6A$

E$)0\mathrm{.}3A$

For the circuit used in the previous problem, find the current through resistor $R_1$ at time $t=$

$.$

A$)OA$

B$)2\mathrm{.}4A$

C$)1\mathrm{.}2A$

D$)0\mathrm{.}6A$

E$)0\mathrm{.}3A$
