Physics - EMI/AC Question with Solution | TestHub

During the growth of current in$\mathit{\text{LR}}$circuit is given by$\mathit{\text{I}}={\mathit{\text{I}}}_0\left(1-{\mathit{\text{e}}}^{-\frac{\mathit{\text{R}}}{\mathit{\text{L}}}t}\right)$

or$\mathit{\text{I}}=\frac{\mathit{\text{E}}}{\mathit{\text{R}}}\left(1-{\mathit{\text{e}}}^{-\frac{\mathit{\text{R}}}{\mathit{\text{L}}}t}\right)=\frac{5}{5}\left(1-{\mathit{\text{e}}}^{-\frac{5}{\text{10}}\times 2}\right)$

$\mathit{\text{I}}=\left(1-{\mathit{\text{e}}}^{-1}\right)$.
