Problem $5$: $(13\%$ of Assignment Value$)$

The switch is in position $($a$)$ for a long time before it is quickly switched to position $($b$).$ The value of the inductors, resistors, and power supplies are $L=0\mathrm{.}35H,R_1=7,R_b=3\mathrm{.}5,E_a=14V,$ and $E_b=2\mathrm{.}5V.$ Treat the inductors and EMFs as ideal.

Part $($a$)$

What is the magnitude of the current through the inductor right after the switch is thrown to position $($b$)?$ Answer in amperes.

$I_L=2\mathrm{.}000A$

$$ Correct!

Part $($b$)$

What is the magnitude of the voltage across the inductor right after the switch is thrown? Answer in volts.

$|V_L|=9\mathrm{.}500V$

Attempts Remain

Part $($c$)$

Which end of the inductor is at the higher voltage right after the switch is thrown?

The right end of the inductor is at the higher voltage.

$$ Correct!

Part $($d$)$

How much energy is stored in the inductor a long time after the switch is thrown to position $($b$)?$ Answer in joules. Hint: first find the current.

$|U_L|=$

$$ J
