Question
Determine the total charge flowing into an element for $0<t<2$ s when the current entering its positive terminal is $i(t)=e^{-2 t} \mathrm{mA}$
Step 1
In this case, the current is given by $i(t)=e^{-2 t} \mathrm{mA}$ and the time interval is $0<t<2$ s. So, we have to evaluate the integral: \[Q = \int_{0}^{2} i(t) dt = \int_{0}^{2} e^{-2t} dt\] Show more…
