Random numbersRLCNHard

S1S_1 has been closed and S2S_2 open for a long time, so the capacitor is charged. At t=0t = 0, S1S_1 opens and S2S_2 closes. Find ii at t=0.5 mst = 0.5\ \text{ms}, in milliamperes.

V0​5 VS1​t = 0C10 µF+−vC​S2​t = 0R10 ΩL50 mHi

Answers within 2% are accepted. Units with SI prefixes work too, like 0.003 A or 3 mA. Use a minus sign for negative values.

Scratch work goes here. Draw with a mouse, finger, or stylus.
