t i(t) if the resistance is 0.2 ohm, the impressed voltage

Chapter , Problem 9RP

(choose chapter or problem)

An LR-series circuit has a variable inductor with the inductance defined by

\(L(t)=\left\{\begin{array}{lll} 1-\frac{1}{10} t, & 0 & t<10 \\ 0, & t \geq 10 \end{array}\right. \)

Find the current i(t) if the resistance is 0.2 ohm, the impressed voltage is E(t) = 4, and i(0) = 0. Graph i(t).
