# Problem: RC Circuit Analysis After the switch has been closed a very long time, what is the current through the 10Ω? resistor?

###### FREE Expert Solution

The charging current for a capacitor:

$\overline{){\mathbf{I}}{\mathbf{=}}\frac{{\mathbf{V}}_{\mathbf{b}\mathbf{a}\mathbf{t}\mathbf{t}\mathbf{e}\mathbf{r}\mathbf{y}}}{\mathbf{R}}{{\mathbf{e}}}^{\mathbf{-}\mathbf{\left(}\mathbf{t}\mathbf{/}\mathbf{R}\mathbf{C}\mathbf{\right)}}}$

After a very long time, e-(t/RC) approaches e-∞.
