Assuming zero initial conditions, the value of $\dfrac{d^{2}i}{dt^{2}}$ at $t=0^{+}$ is $\dfrac{V}{L} \\$ $\dfrac{-V}{R} \\$ $0 \\$ $\dfrac{-RV}{L^{2}}$ Electric Circuits gate2015-ee-2 switching rl-circuit zero-initial-condition + – makhdoom ghaya asked Feb 11, 2017 • edited Oct 2, 2020 by go_editor makhdoom ghaya 9.4k points answer comment Share See all 0 reply Please log in or register to add a comment.
