GATE ECE 2014 Set 2 Network Theory - Transient Response Question 16 English

$$I(t) =\frac53\left(1-e^\frac{-t}\tau\right)\;,\tau=\frac23\;m\;sec$$

$$I(t) =\frac52\left(1-e^\frac{-t}\tau\right)\;,\tau=\frac23\;m\;sec$$

$$I(t) =\frac53\left(1-e^\frac{-t}\tau\right)\;,\tau=\;3\;m\;sec$$

$$I(t) =\frac52\left(1-e^\frac{-t}\tau\right)\;,\tau=\;3\;m\;sec$$
