Question

In the circuit shown, the switch $S$ is open for a long time and is closed at $t=0$. The current $i(t)$ for $t \geq 0$ is

 

• A. $i(t)=0.5-0.125 e^{-1000t} \mathrm{~A}$
• B. $i(t)=1.5-0.125 e^{-1000t} \mathrm{~A}$
• C. $i(t)=0.5-0.5 e^{-1000t} \mathrm{~A}$
• D. $i(t)=0.375 e^{- 1000t} \mathrm{~A}$
